I'm homeschool so yeah and it helped me too so much
same i’m homeschooled
Me too
I never heard cube roots before... thanks school
Same
you saved my life tysm!
I'm glad this video helped!
@@TheOrganicChemistryTutor can you reply to me plz
@@lilsumowx650 lmao nice man
Your a total genius, I wish you had your videos in order for algebra and pre calculus as well as calculus and all other math possibles like chemistry, and geometry. Thank you for sharing your videos and all the information in them. I only wish you had a video or cd or book with your knowledge and way of doing math I could purchase. Thank you sooooioooooooo much.
OMG YOUR AN ABSOLUTE GENIOUS THIS HELPED ALOT.. KAFJSAOHOAFH
KAFJSAOHOAFH
Ikr
Genius?
KAFJSAOHOFH????????
🤓

Thx a trillion times you helped me thx thx thx big fan 😁
My man, OCT
Facts
Think you sooooooo much!!! I love your vid. and your videos is very very very helpful and useful. Thx
Best maths teacher ever. You explain it so simple and easy to understand as a 9th grader
Thankyou you saved my life😁never thought I would understand this
THAAAAAANKYOU
thank you i actually understander from this video since i have an exam tomorrow
MR. Organic Chemistry Tutor, thank you for another awesome video/lecture on Square and Cube Roots. Taking Square and Cube Roots of small and large numbers are excellent tools to store in our Mathematical tool box.
KID🥸🥸🥸
Bless you! You have taught me something that my instructors could not! Thank you so very much 💗
love your channel bro you cool I never understand when my teachers or my mom teach me about this when I saw your channel I can understand this completely it was like a magic you rock man
Im study from your channel for maths test tomorrow hopefully I succeed 🙏🏽❤️
Hi
Video pure
Aap hamen video send kar sakte hain chitthi bhi ho thankyou ham
Superb video. Understood all concepts ❤❤❤
Man, you've helped 2 Mil people. Great job
Best maths channel
He is on Udemy, let´s go purchase his courses as a form of appreciation. You are a brilliant tutor.
THANKS ALOT CHEMISTRY TUTOR YOU ARE THE BEST IN MATHS IM SURE AT SCHOOL YOU ARE AN A+ STUDENT
I have a math test tomorrow and this helped so much thank you
I have a math test tomorrow ahaha
Thanks for the help. I've got my first math test tomorrow!
samson m same
How was your test? BC you wrote this comment before 3 weeks 😅
Right how was it?
I am not exaggerating but i have never seen this kind of teacher in my whole intire life. And u are the best person that could possibly be exist
Thank you!
Omg tnq I have Xam in 20th and u helped me soo much.
Have a math test on this tomorrow, thank you!!
Lets not talk about the fact that I’m failing pre algebra and this is gonna save me 😭😭
im just failing everything
Thanks this helps
he teaches better than all of my math teachers combined
Thank You! This Helped So Much
Thank you so much. This cleared all my questions.
Thx this should be useful for algebra
This video is great i appreciate it💕
I’m so mad because I was stalling to do my homework only to figure out that it was so easy😭😭
Thank you so much
please make videos on approximation techniques for tough number..which includes. roots, decimal division,cubes, multiplication etc
you are one gienuse i wish you were my teacher
Waw I really enjoy this maths class
Thanks
OMG These helped me SOOOOOOOOOOO Much and Now i definitely know about Square roots and Cube roots!!!!! Thank you so much
you deserve so much this helped so much pls dont stop
This guy is an angel 😇
This man saved my grade in 7 minutes😂😂😂😂
hehe these are some real good vids. i'm sure i'm gonna pass the exams i have coming up.
In half a hour my CAT is there THANKS A LOT
Your examples are easy to understand now im going to flex on my friends .
Im a 6th grader btw
AYO?? YALL TAKE THIS IN 6TH GRADE??
I always watch ur vids when i need math
Thx man
So the imaginary "i" only applies to square roots?
Yes, it does!
Because real numbers cannot be squared and equal a negative number. (I.e. -3 x -3 = 9). However, imaginary numbers (which are created outside of the normal and "real" numbers) make the square root of -1 possible, but that does not make it "real" or true. Try looking for an "i" sign on your calculator. But yes, it only applies to square roots, yes.
Amazing but I have different types of questions...
same
Best video
ive never understood math as much as i do now
OMG!!! Thank you so much!! It helps me a lot!! This is much easier than I thought 😂
You are amazing
Thank you!!!! this makes so much sense
Can you please show how to solve for imperfect cube by long division. Would be very helpful, thanks!
Bruh.....❤️
Thanks for the help ma dude
2:17
That'd actually be (3i)/4
Yeah i thought the same thing
Cube root is harder than algebra for me
this shit is so fucking usef! thank you sir!
4:11 I didn't get it, how did u got -27 it has to be positive 27
Please advise fastsr today tell me please
Because the - is inside the square root, go back to the start of the video there you will find all 3 examples of when a number is postive 9, -9, or 9i
Cube root of 27 is 3 because 3x3x3= 27. So cube root -27 is -3 because negative 3 multiply negative 3 gives you positive, now you have to multiply another negative 3 because -3x(-3)x(-3)
and it gives you negative -27 because positive multiply negative gives you negative
Working:
-3 x (-3)= 9
9 x (-3)= -27
I’m also confused on that question
Om the way you say three is sooooo cute
I have an exam tmr 😅🤣🤣😅😅 and Im learning now
What's the cuberoot of 4.38
3:47
I kinda don’t get the decimals one but thx
sqrt (-25) = error
Why is there a I?😭
Im really late but isnt sqrt(25) plus or minus 5? Because 5^2 is 25 but also (-5^2) is 25
Square root of -25 is 5i but cube root of -27 is -3 and not 3i why?
My teacher literally didnt teach us all of the evaluation and just hid all and show the easiest to us student face
When ur teacher just was hard to understand
what year is this or grade?
High School
Square root of -25 is 5i but cube root of -27 is -3 and not 3i why?
My teacher is kinda 🗑 so tysm
ooo armyy
hey which app do you use can you tell plsssss
sqrt (-25) = invalid input
4:15 I’m so confused on this one
4 times 4 times 4 is 64
4:14, wait... I thought if you multiply 2 negatives it becomes a positive? Can someone answer.
There not together the brackets are seperating them
I’m dumb
i didnt understand :(
This taught me but you go to fast if you went a bit slower and taught the steps by step I would've liked the video
Bro where tf did you find 6, how tf, can u explain? (from 3√125/216)
Bro just do cube root of 125 and 216 which equals to 5/6 easy
Just separate the number and find cube root of the numbers then put them back in place
what will be the answer for cube root of 8 decimal points🤭
whats i
Bro this is NOT 13 year old square root bro wdym 9 i 😭🙏
