Law of indices (all index laws) - Math

6 index laws that you need to know to solve any problem requiring indices.

List of all indice laws

Rule 1 x^0 = 1 (except for 0^0)

Rule 2 x^-n = 1 / (x^n)

Rule 3 x^n * x^m = x^(n+m)

Rule 4 x^n / (x^m) = x^(n-m)

Rule 5 (x^n)^m = x^nm

Rule 6 (x^n/m) = msqrt(x^n)

Some of my friends said not to watch this as it was confusing. I have absolutely no idea what they're talking about. This was so clear, and at first, I was worried about, power of and dividing and multiplying? Yea, some things I am definitely not strong with. I understand so clearly now! Thank you so much!!

With index laws instead of using 'x' it is more common to use 'a'
