What is a simplified form of the expression (5^2) - ^2Divided by 5^3

5^ - 7 = 1 / 5^7

Step-by-step explanation:

(5^2) - ^2 / 5^3

We know that a^b^c = a^ (b*c)

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

5^-4 / 5^3

We know that a^b / a^c = a^ (b-c)

5 ^ (-4-3)

5^ - 7

If we don't want to use negative exponents

We know that a^ - b = 1 / a^b

1 / 5^7
