Index Laws w/ Algebra

[@gianthcr6173]

4:26 To anyone watching who is wondering why any number^0 = 1, we can use the 2nd law he mentioned in this video. As an example, I will use 2^3 divided by 2^3. Since a number divided by itself is one, we can say that this problem is also one. But if we subtract the powers, it will be 2^0. Hence, why it is 1.

6 years later, still beyond helpful. Thank you for these videos!

9 years later still very helpful thank you this helped me alot

[@shenisebalkissoon4670]

I love the way you teach Math it's better than my teacher.

[@baptistebauer99]

Thank you sir. I understand that most people watch your videos to study and get a recap on the topics, however, I'd like to thank you today for showing me how to teach those topics. I've become a math teacher this year, and watching you explain the topics give me a very solid idea as of how to make the kids learn and grow. You're awesome! :)

why am i watching these videos up until midnight when i hate maths itself?

[@samsav2866]

Because you had a test on it most likely

I’m an adult student learning about algebra and indices for the first time, it all looked like gibberish on my work sheet but this video helped it all make sense, THANK YOU SO MUCH!

8 years later and dis video is STILL helpful

[@MundaneMuser]

Watching this was like being back in high school. I can literally feel the acne and bad BO coming back.

[@lachlanmcgilvray9007]

Thanks, helped a lot. Still don't understand why there are letters in math though.

[@destroyingbiscuitmlg7895]

Lachlan McGilvray yeah Ikr

[@lewisjones284]

Because it's the shortest thing you can assign to a number that you don't know the value of

[@Abstractperson]

lol

[@finnanfilms5625]

@Lachlan McGilvray hi! 1 year later, the reason is because the letters are substitutes for the numbers themselves ^^

[@itsmesai2429]

It's just like a Question Mark.. If you don't know the value or something, you put a question mark, right? Instead of a question mark, mathematicians use letters.. Don't overthink it.

[@thanuthathuvanathan725]

Teachers take a whole lesson to explain, but he just took 8 mins. understand it so clearly now

[@princeahuja382]

Best teaching sir :) It was really nice class :) I have same experience from Vidya Guru teachers as well. Their all teachers present the exam relevant important questions only.

I so wish i had this teacher. What school does he teach? Since i am aussie sooo

[@codingeasy1158]

is in this video he is teaching to the college students of australiya , because in india this things we use to learn in 6th ( 10 year old student) grade only . not saying a ny thing to the sir because he is the best teacher ..................

[@katiedrew6673]

It's obviously a school haha

[@artemisiliopoulou5487]

god bless you, you are better then my maths teacher

How does the index law a^1/2 = sqrt(a) apply in these situations: • a^1/2 + b^1/2 ▪︎ isn't sqrt(a + b) the same thing? • sqrt(a^2 + b^2) ▪︎ isn't this the same as sqrt(a^2) + sqrt(b^2)

[@baptistebauer99]

Hello :) I hope I'm not too late with my answer. a^1/2 + b^1/2 = sqrt(a+b) is NOT a true equality. One way we can see this is by plugging in numbers and see what happens: let a=9 and b=16. We would get 9^1/2 (which is 3), added to 16^1/2 (which is four). Uppon adding them up, we get 7: 9^1/2 + 16^1/2 = 3+4 = 7. What about sqrt(a+b)? This would be sqrt(9+16) = sqrt(25) = 5, which is different than 7. The equality does not apply. Regarding the second point, nope, the equality is still not mantained. We can apply a similar argument. Using the same values, sqrt(9^2+16^2) = sqrt(81+256) = sqrt(337) ≈ 18.35. sqrt(a^2)+sqrt(b^2) = a+b = 9+16 = 25. (see note regarding the first equality). We can see that the values are also different. The equality is not true. Note: technically it should be |a|+|b|, but OP might not be familar with the absolute value, and the values are positive anyways.

I thought that last problem was a trick. I solved it right once and wrong the a 2nd time before getting your solution. gotta' remember I shouldn't overthink it.

One might argue that 18 p^7 / 6 p^3 = 18 * p^7 / 6 * p^3 = 3 * p^10. To avoid confusion it should have been written like this: 18 p^7 / (6 p^3).
