Square and cubed roots
Breaking it down
Cubed just means that instead of multiplying A x A, youre going to do A x A x A. Three A's and the cubed root for 64 is:
Because 4 x 4 x 4 = 64.
The three is there like a 2 would be there for squared root. And if the is no number there then we always assume that we are squaring. But the three is there so were cubing.
