Question

How do you do permutations?

Answer 1

Permutations are written as nPx where n is the number of total choices possible and x is the number of choices that will be used. This is calculated as nPx = n! / (n-x)!.
Permutations represent the number of ways we can choose x objects from n possibilities where the order of selection matters.

Answer 2

Heres an exapmle:
5^2
Would be 25 (5x5)
Because you take the number at the top and multiply it by the base to however many times.
Hope this helped !!
