Sir please can you tell me log 0.00005 ??🥺🤧
And log 1/0.00005 ?

the only flaw is the sharp noises when he talks
I wish you could sit in on the bad math classes in the US. My professor took 2 days to explain this and made it sound impossible. You really are the best tutor on YT.
This new generation is lucky because it's easy to find best tallented and knowledgeable teachers on line and easy to get all information related to your study, assignments, workshops and any topic ideas.

BRooooooo this is wild. I learned so much! My school's online learning site is such a waste of time. Why'd I just learn an entire unit in 10 mins. This is how education should be.
Exactly... I spent a whole hour studying this ads 22seconds into the video i understood!
@@prettygrlstarr totally true!
u didn't, u just memorized, do u remember it now?
@@Saytsee yes lol. It's not that hard to forget.
@@Gemicideee did i ask u?
I took a college alg class at a community college. You were VASTLY superior to their instruction. I used your videos and got a 95 for my final grade. Oh! And I had been out of school for over 12 years.
Well done bro
Well done
Well done bro
The first 31 seconds of this video taught me more than what I understood in class. Thanks so much!
True
loi elooooooo🤣
the first 32 for me
i thought u were being sarcastic but u werent caping
Funny how I didn’t understand this in a 1hour and 30 minute class but I can learn it in 10 minutes from this guy school is so useless
:)
Depends upon the teacher
PikachuBosss Bro my teacher is the worst I failed his class for two semesters but when I gave up on his and tried to learn shit by myself (by za internet) I literally got an A
Everyone has different learning styles. I know personally that have aced classes that many of my classmates struggled with, and conversely have struggled with classes that others seemed to have no issue with. The problem is that everyone in a classroom is just expected to learn the same way.
Kinang ina mo
0:16 - FIRST EXAMPLE ---- " LOG _2 of 16 " is asking how many "2" s NEED to be MULTIPLIED to get to 16 , here we see that 2x2x2x2 = 16
so therefore " LOG_ 2 of 16 = 4 " because we need to multiply four "2"s to get 16 .
1:11 - log _4 of 1 - " log" of 1 is ALWAYS equal to ZERO
1:19 - LOG _ 7 of 7 , when BOTH numbers are the same the simply "cancel out" and will ALWAYS equal to "1 "
1:36 - What to do if you're not given a base ?? ( in this case , LOG of 1000) ** if you're NOT GIVEN a base , the base is ALWAYS assumed to be a "10". with that in mind LOG (1000) becomes >>>> LOG _10 (1000) AND LOG _ 10 (1000) = 3. , because 10x10x10 = 1000
2:17 - What about " LOG of 0.0001 " ??? * as previously discussed when we have no base its always assumed to be "10"
so LOG_10 (0.0001) = - 4 BECAUSE the " 1 " in " 0.0001 " is in the " ten thousandths " place and
10x10x10x10 = 10,000 BUT we know its NOT " Ten THOUSAND " its " Ten THOUSANDTHS " so instead of 10^ 4 its 10^ - 4
2:35 - QUICK REVIEW , and noticing the logarithm pattern
LOG of 1 = 0
LOG (10) = 1
LOG (100 )= 2
LOG (1000) = 3
LOG (10,000)= 4 *** notice how the number of "zeros" correlate with the number on the right ** for example " 10 ,000" has
FOUR " zeros " and LOG of 10.000 = 4
so with that in mind whats " LOG of 1,000 ,000 " ?? well we know that "1,000,000 : has SIX "zeros" in it , so therefore
" LOG of 1,000,000 = 6 "
3:28 - Logarithms with decimals ( further explained ) as discussed above the number of "zeros". directly correlate to the number on the "right"
so >>>>. LOG of 0.1 = - 1
LOG ( 0.01) = - 2
LOG ( 0.001) = - 3
LOG (0.0001) = - 4
4:04 - whats " 7 LOG _ 7 ( 38 ) ? , if you ever get this odd question on a test , SIMPLY CANCEL the two numbers out ( in this case we'll cancel the two 7's out ) and the answer will equal to the the other number ( in this case it will equal to = 38 ) so " 7 LOG _7 ( 38) becomes >>> LOG (38)
and LOG (38) = 38
4:51 - Working with fractions in a logarithm question EXAMPLE we know " log _ 3 of 9 = 2 " but how would our answer change if we had
LOG _ 3 ( 1/9 ) ?? Well , actually , "LOG _ 3 of ( 1/9) = -2 " * you have to flip the fraction( * *** And the NEGATIVE EXPONENT will cause
the "9" to move from the TOP to the BOTTOM ( 9/1 >>>> 1/9 )
5:35 - what if we flipped the numbers ?? if " Log _ 3 ( 9) = 2 " what's " Log 9 _ ( 3 ) " equal to ?? well SURPRISE SURPRISE there's a "2'" involved
" Log _ 9 ( 3 ) = 1/2 ) " * you have to move the "2 " from the TOP to the BOTTOM " ( 2/1 becomes >>> 1/2 )
5:54 -- whats " Log _ 9 ( 1/3 ) equal to ? well know that " Log _9 ( 3 ) = 1/2. (so knowing that we have to "flip" the fraction * turn 1/3 to 3/1 *
" Log _9 (1/3 ) = - 1/2 ** REMEMBER , a NEGATIVE exponent ALLOWS us to FLIP the fraction ***
6:06 - ANYTIME we have a fraction , our answer WILL be NEGATIVE , and anytime our "base" number is larger than the second number
EX : " Log _ 9 ( 3) our answer WILL be a FRACTION
6:44
7:07 - Review questions ( pause and try to answer questions )
8:57 - MORE practice questions . ( pause and try to answer questions )
thanks. much appreciated

I don't understand ANYTHING that my teacher says, but you always make everything crystal clear. Thank you
I love how there are so many videos for one topic cuz im really bad at math and dont understand fast enough and have a bunch of videos from the same teacher is better than having to look for other recourse so THANK YOU!!!

Did this in high school but now I’m cramming for a college test tomorrow. Thank you for this!!!
Best teacher ever in the universe for trig,calculus ,logarithms and all concepts !
I’ve been learning this for two weeks and I finally understood it in one lesson from you
I just want to say THANKYOU. You are phenomenal at explaining things in a simpler way that I can understand. I was literally crying taking one of my tests for my college math class I am in. I would listen to the lesson over and over & still did not understand. I feel like the videos my teacher provides make it way more complicated than it needs to be. Anyways, you have saved my sanity.
you are literally saving my life on my exam
Your really good at what you do and I am honestly waiting for you to reach 10 million cause you definitely deserve it
I've watched you grow from 1 million to 5 million
Yo, Yes.
I'm 67 and a college graduate from a well known university in California majoring in Biochemistry and biology. From what I remember, this is the most succinct explanation of Logs and how to work with the basic fundamentals! Thank you who ever your are!!
you shouldnt like your own comment
@@terry1989 Since I made this over 11 months ago, I barely remember it. My comment stands.
You are literally the reason im passing math. I’m so grateful for u
This really helped in my Math! I've always struggled on it since day one, thank you so much for the help. You earned yourself a subscriber!
i had an algebra sub today and i didn’t understand his teaching at all. and he was so annoyed with my class. so that’s why im watching you because you explain everything so much better. thank you so much!!
I missed this lesson in Algebra class because I had an AP test today. You came in clutch thank you
it's the way these are taught that makes it so much more digestable. he uses a show dont tell method rather than showing the formula with all the variables which just looks confusing, and rather he just does the problems and elevates them in difficulty so that there's an actual grasp to the practice rather than a focus of concept which i think is so much easier to learn from.
Well said!
It helps retaining the lesson then working with different formula will make the sessions bearable
learned what i would spent years on and paid for in 60 minutes with taking notes. thank you so much!
I recommend You this playlist ruclips.net/video/6Cy13xamkks/видео.html&ab_channel=BiPhysiMath-Special
istg, my teacher posted a 1 hour 47 minutes video trying to explain this, and i got more confused that i was before, this dude was able to make me understand all of that shit in 10 minutes, damn.... your our hero istfg 😂😂
@Alpha Dog nope, 10th, mn wen enta?
I simply love your tutorials. You make it easier to understand than my professor at times. I have watched your tutorials on a few of the classes that I'm taking in college. Thanks for your time and patience in teaching.
These lessons are awesome, and I don't even have to pay you!!!
Who’s still watching in 2025 ?😔💪🏻
thank you, i gave up in my math class and im trying to get back on track and this helps quite a lot
Hi
when you're watching this because the online math class that you were put in for this summer program is too hard so you don't understand anything in there so you have to watch yt videos to help you learn before you have to turn in an assignment due in two days...AHAHA that's me.
The king has saved me once again
Thank you for this im writing further maths exam and I rally needed to learn logarithm
Thank you! You are a life saver!
I didn't understand how logarithms worked for almost 6 months. After our math teacher drastically tried to explain it to us.
But, finally, I have understood how it is done in the first 5 minutes of this video!
who's watching this 0.01 second before exam? 💀
Nah after I failed it and need to retake it
i am wachting it like 2 years before no exaggeration.
U r the only one😅
@@austinyates1054 i came back after i failed and this is the second time 😂
nah i'm just learning it for myself cuz i'm a nerd
THANK YOU SO MUCH-I learned so much more in these ten minutes then I did in an hour long class. UR THE GOAT
Thank you so much sir . I really appreciate you effort . You are really a great help for many students who are busy with kids and family life where they don’t neighbors time to spent on other resources to better understand the concept . You video and short and very well explained. I am praying so hard for your success and god will reward you for the service ❤🙏
the first minute of the video taught me more than my teacher did in the entire week we studied the subject, thank you.
Learned more about logarithm functions in 10 minutes, than in all of college algebra.
OMG twewy fan in the wild!! Hiii hope you're enjoying NEO
As a 12th Grade I really enjoyed the video. Greetings from Tire Kutsan Anatolian High School!
Just entered high school and I am already being introduced to logarithms😭hope u do well.Wishing High school students 🤞🤞.
There is some kind of aura that learning for yt has which isn't in school classes which makes learning online more interesting 😂
Thank you so much most math teachers are so terrible at explaining and always explain it like I already know how to do it and don’t tell me the little stuff like you do. I appreciate you
It’s 4 am and I’ve 500 hw problems to do ⚰️
what nationality are you?
wtf 500 problems burh i feel for you nobody has that many homework problems i mean theres only so many you need to do until you understand...?
dildo baggins in college i have to do 200
I love this guy😍😍I easly understand him😍😍
thank you so much, it is incredibly simple yet understanding when you explain things. You are helping a lot here.
Insane. You will be everyone´s guide in life
He makes it so easier to understand 🔥👌
literally the best teacher there is
Thanks.Ur video flow makes me understand it very well.
Watched many videos, his voice, the layout and order of explanation. Fantastic!!
Well explained and excellent pace. Thanks!
As a hs freshie taking the accuplacer so she could take statistics second semester who also has no idea what log stood for 10 min ago this helped me sooooooooo much thank you sooo muchhhhh❤❤
Thank you so much for sharing! This was so helpful!
You’re a living legend for this fr
4:30 i found this the hardest rule while studying.. but after watching how he solved it i could not stop my laughter
hey, i have a question, can you explain the rule? because I still don't understand it, especially that my calculator keeps saying otherwise
His voice makes it even more intersting and easy to understand it.
I have wasted a month trying to understand this topic because of my addmaths teacher. there are some days where I felt like giving up trying. I was so stressed and I ended up not studying for this topic at all. The textbook is also impossible to understand. This video had helped me to actually understand this topic. I am very thankful for this guy !! He is a hero for every suffering students .
Good job, remember, if your serious about learning or passing something then you have to put the work in yourself. Thats where youtube comes in :)
I think this guy has a teaching gift
Pro tip: Using the logarithmic property of log(a/b)= log(a)-log(b) is amazingly helpful. So with log base 81 of 1/3, is becomes 0 -1/4.
U just made me pass my math class bro thanks 😅
your explanation is better than my professor in college.
I really appreciate you man...thanks!
I never understood why your videos were so popular. I'm just a slow learner I think. After some fundamental understanding of the topics you cover I'm able to more deeply appreciate your videos. Using your videos to learn new concepts doesn't work for me, but using you videos to reinforce concepts has been extremely helpful!
Stop scrolling through the comments and listen!! You’ve got a test tomorrow!!
yes i do
No i don't
This has taught me more than my teacher ever has it took her a solid 2 weeks to explain what you did in a 20 min video i hope you get a nice paycheck from RUclips friend
Dude you made my life easier
Not currently learning logarithms as I'm not in that grade level yet but I was interested in them and wanted to understand them better. This video helped so much that I started to pick up what you meant in the first 2 minutes. Thanks for this.
same bro
You are great sir
Since I came across this video, logarithms has become easy for me.

Struggled with logs for YEARS, totally confused, totally unable to remember how it works. Just saying "How many times do you multiply 2 by itself to get 8?" i.e., "How many times do you multiply the base by itself to get the number?" -- it all just went "CHUNK" right into place and I was able to answer all your example problems before you worked through them! Amazing how just framing an explanation differently made all the difference (for me -- maybe your explanation wouldn't work at all for people who get logs easily by the other explanations). But THANKS! Subscribed and will let you help me tackle the other things in your series!
1:50 I would like to mention that it isn’t always assumed to be a 10, it depends on the context in which it is used.

What if it's log 8? 10 raised to x = 8. How can I answer it? Do I just do trial and error? Is there a possible computation to make it faster? Thanks for this tutorial!!
log(8) is going to have a value that’s going to be in between 0 and 1. You can try to put this on your calculator. For exact answer, we just leave it as log(8).
Thank you for saving me
On my test tomorrow
9:57 Why did you put ¼ right there?
3 to the 4th power is 81, when your reverse it and the base becomes 81, it turns to a fraction 1/4
