Question

What is 5^-3?

Please I really need someone to explain to me what do you do when there is a negative sign in the exponent. Thank you :)

Answer 1

Answer: 1/125 or 0.008 (simplify 1.125 or should I do it?)

Explanation:

Well, when there is a negative sign in the exponent you only move the negative exponents. Moving only negative exponents is recommended because using this rule, you multiply two exponents with the same base and add their powers.

Answer 2

1/15

You take out the negative and do the regular equation but turn it into the fraction with one as the numerator and the solution of the exponent as the denominator.
