Example: 2^5 = 32 because 2*2*2*2*2 = 32

but why isn't -1^2 = 1 ? isn't -1*-1 = 1?

true

Step-by-step explanation:

(-1)² = -1×-1 =1

and -1^(-1) = 1/(-1) = -1

use x^(-1) = 1/x

-1^2=1

Step-by-step explanation:

-1^2 is 1 but if you try with a calculator and you write -1^2 it's -1 because the calculator consider just the 1. If you put the parentheses it is (-1)^2=1
