Algebra - Simplifying Radicals (part 2)
HTML-код
- Опубликовано: 10 сен 2024
- I want you to find this if you're looking, so, what we're doing is called Simplifying Radicals, or Simplifying Square Roots. Specifically, we cover how to take the square root of variables, as well as how to simplify (aka "rationalize") square roots in the denominator. YAY MATH!

Only math videos that I can understand and make the whole way through. I used to not like how you can hear his students in every video but now I like it because they ask a lot of "obvious" questions that I'm wondering myself lol. Most math teachers don't think of clarifying some simple things so it's nice that most of the things I'm wondering myself are usually asked and answered. Also, I like how he is always very respectful when answering these "obvious" questions. A lot of teachers get frustrated, which is understandable, but I don't think I've ever seen this teacher get frazzled.
right?!
The classroom has a very respectful atmosphere, but the students are the center of attention here. I feel like in this video he is reviewing the general concepts before they will be taking a test.
yeah this guy is a miracle first i actually understood the whole thing second he is ((a fun math teacher)) yeah that is like IMPOSSIBLE
I am 35 yrs old and watching this for my math class. We are doing Radicals. I was so lost. Thank you for taking the time to make these videos. I want to cry. I wish everyone taught like this. Numbers are confusing for me.
I come here after my math class to learn math.
These are very helpful, especially when you're absent a day from school and miss part of the lesson :D
Keep up the good work
What is wrong with me? Why are your videos making me enjoy math!?
SAME
maths are actually fun
Honestly I’m 26 years old and back to college and having the first formal math class in over a decade. I really am so sad I didn’t have a teacher like you when I was younger. I hated math and I felt like I wasn’t as smart as my friends cause I just couldn’t understand what our teacher were was saying. Watching these as an adult has made me appreciate mathematics so much more than I ever thought possible. Thank you so much for this content @yaymath
This dude is the GOAT
Can you please make playlists for the different chapters like geometry and algebra and algebra 2 to make it easier to navigate
superMHful working on it, thanks for the suggestion

how would z to the 100th be 50 sqaure root of z
+yaymath with ur 2 over 2 square root 3 couldn't u just cancel out the 2 on the top and bottom leaving u with only square root 3?
+lexbogie1 The 50 square root of z is the reduced version of z to the 101st. He took the 100th and multipied by 1/2 to get rid of the square root. That gave him the 50, then he multiplied by the square root of z left over inside.
Due to everything going on, my middle school is online teaching. Luckily, my math teacher sent us parts one and two of this. This was much easier to understand than I was expecting! I'm subscribing right now.
i was struggling over my math homework and i couldn't even rationalize where to start. your videos make so much sense to me. thank you
Every time i have a question some kid asks it, and I'm like "Oh thank God". These vids are awesome man!
UGH THANK YOU SO MUCH I'VE BEEN HAVING TROUBLE WITH THIS FOR SO LONG THANK YOU THANK YOU THANK YOU
I have a good and chill math teacher but I haven't had math in a week bc of testing (on testing days we can't move classes until everyone finishes testing even if we aren't the ones testing) and I have my algebra eoc tomorrow so I rlly needed this
This video helped my with my college statistics class, thanks man!
Dude you are the best!! Every teacher in the world should have to watch and match your enthusiasm!!
Gosh your so helpful, I wish in my over 20 years of education a math teacher took the time to help me understand math the way you do with your students
Man it’s a good thing I found this because if I hadn’t I would’ve gone into my algebra test on radicals knowing absolutely nothing, (the test is tomorrow) and I’ve been trying to get these down for two weeks. Couldn’t do it. Got every single review question wrong. And I’ve learned more in 30 minutes than I did in those 2 weeks
Same, man
I wish you are my Math teacher. Sigh~~~
Your wonderful. I've spent so much money on tutors, you've clarified a lot for me in just one of these.
I love these videos and I'm studying to be a teacher too. However, these have made me realize I do NOT want to teach teenagers lol.
Thx man, my Math Teacher told me about you and she told me to check this channel out. Its great, thx for helping me out.
You just saved my academic life. Thanks :D
Thank God for you .You're a great Teacher .
ha.. I wish you were my professor!! new subbie!!
I understand now my algebra teacher a bad teacher no offense 😬😬but this guy he makes it fun and he makes me understand it more
What school does this guy teach @? because I wanna enroll there!
I would pay to have you as my teacher!
The only way to get such scenarios is where the root is of a perfect square anyway, so the solution is to just solve for the square root (in this case, the root of 4 is 2). The answer in this case would just be 3/4.
I have a quiz on this tomorrow. Thank you for helping me
No, because the root of 4 is 2. The denominator becomes 2 + 2 = 4.
However, under what he was talking about, yes, because the root of 4 - 2 is 0, so you would be multiplying the denominator by 0, which you can't do
I understand the whole thing. I wish my algebra teacher is like him.
These girls act drunk in every damn video
I think they wanna fuck the teacher haha
😂😂
@@zackbanin5655 same
Thank for teaching. Sayar!
ohhh😇😇 student seem so happy to have u as their teacher....
awesome..catching on to radicals now! Thank YOU!
3:54 i get that if you have Y * Y with exponents you add the exponents but what if it is Y * X with exponents? what do you do?
your a great teacher
in the end of the video you write down an example that you don't solve and I tried it myself but I'm not sure. Correct me if I'm wrong but is the answer 3/4? I got the square root of 4 and added it to the 2 or do you still have to do the whole negative twin thing?
Looking at 2/(2+sq.rt.3) and the lesson on Rational Exponents, how come the problem and (2+sq.rt.3)^-2 aren't mutually equivalentl? I remember that negative powers turned into fractions such as the problem, but why doesn't that solve the answer? The root isn't in the denominator any more. :/ Is it because we're simplifying and not solving, or am I totally missing something?
@ Humberto Madrigal I think the answer is 9x^3y^10 to the square root of 2x
doesn't necesarily need to be a perfect square, it could be square root of 5 + whatever digit is the actual square root of 5. then you would pass right through that step without ever realizing you put a zero in the denominator. (unless you know the square root of 5 off hand.)
teacher is fun and goes slow into the de concepts. good looking too. ;)
Thats what i was refering to, "what he was talking about"... not the original question. so if his technique doesn't work there, what do you do?
That is totally Radical dude!!!
LOVE MATH!!!!!! YES.......I LOVE MATH
when you asked for any questions about the top of the fraction, 15:07 of the vid, how did you get the 4-2sqrt of 3?
Thank you this helped.
7:00 - 12:00 Rationalizing the denominator!
Thank you very much sir
Your my hero
I wish I was in this class lol so much fan thanks man for this channel
Great!
nice i learn new thing!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
good job cheten
thx
question: may i subtract the answer 4-2squareroot of 3 just like 2squareroot of 3
In 11:27, you can simplify (6 radicale 3/3)? How
if you do the last one... doesn't that leave you with a zero in the denominator?
(4^1/2+2)(4^1/2+2) = 4 -2^1/2+2^1/2-4 = 0?
THANK YOU FOR THIS!
Good teaching!!
@yaymath hello, I'm a little confused about the perfect square part, where did 3 and 49 come from? Just because 3 is the root of the perfect square?
hi, this is a late response lol but if you still don’t know the answer I’ll be happy to help u! 49 and 3 is there because when you multiply them, you get 147.
goof job thank u soo much
THANK YOU SO MUCH !
awesome
where did you get the 3Z inside the square root (in the final answer)
What about if the problem is the fourth root of 162x^7 y^20 >???????? anyone hekp please
What grade level is this?
i think all of us want this guy as our teacher
yaaaymaath! yaaaaaymath!
very clear thank you sir :D
AND I UNDERSTAND THANKSSS.
what happened to the 48?
where 3z came from? reply, thx
I tho 7 can't be simplified anymore?
what grade is he teaching?
at 16:40 aren't you suppose to subtract 2 from 4 so the final answer is 2 square root of 3?
I know this is a late reply but you can't do that because they're not like terms.If it was 4 root 3 minus 2 root 3 then you would get 2 root 3. You can ONLY add or subtract like terms.
DarkForce852
Yes it make sense. Thanks bro. I'm also al pro
+craig I had the same question, thank you!!
+Jennifer Goich your welcome
What happens if it's ^3|625a^7 :(
found it =]
basically, I've got a problem: can u talk me through square rooting 2809
thanks :)
6:40 lol
11:27 pop smoke reference from the past
where did you get the 3z???
6.26
AS THE SQUARE ROOT OF 3 TIMES THE SQUARE ROOT OF Z IS EQUIVALENT TO THE SQUARE ROOT OF 3Z
ohp never mind I see you just foiled it. haha
I wish you are my math teacher :((
11:30 why are you simplifying?
Tristan
Because 6 divided by 3 equals 2
Last
I hate math but you make it esey
Plot twist the kids arent real they are just sounds off a sound board
Que Que Que Questions!
((y^3))^3 = y^9 I know teacher knows this, but I didn't see him mention it when a related question came up a around 3:50 and I had to turn off the video.
Second!
put him in charge of national education!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life john 3 verse 16
yay math its 2016
Splitoroni 1:30 hahahahahahaha
