Question

Select all that are equal to 5³x 5⁻⁷

Answer 1

Answer:

The third and fifth are correct

The second one is NOT correct

Answer 2

Answer : the second and third ones are correct.

explanation for the second one : they don’t accept negative exponent answers. by putting a “1” on top, it just means that you’re simplifying the problem and you’re just taking the 5^-4 and making it positive

explanation for the third one : it’s just the answer to 5^3•5^-7 but not simplified yet
