Which expressions are equivalent to this exponential expression?

answer: simple: 5^4 is 625, while 5^-2 is just 0.04.

5 cubed (5^3) is 125.

if you multiply 625 and 0.04 using a calculator, you'll get 25, and if you divide 25 by 125, it'll basically simplify to 1/5.

so your answer will be a. hope that !
