Question

Can someon help me with this?

Answer 1

A and D

Explanation:

`(5^(-2))^(2)=5^(-2*2)=5^(-4)=1/{5^(4)}\\\\5^2*5^(-6)=5^(-6+2)=5^(-4)=1/{5^(4)}`

Answer 2

5^-2 ^2

and 5^2 * 5^-6

Explanation:

There are 4 (1/5)'s multiplied together so

(1/5) ^4 = 1^4 / 5^4 = 5^-4

and

we know that 5^-2 ^2 = 5^(2*-2) = 5^-4

and 5^2 * 5^-6 = 5^(2-6) = 5^4
