Question

Rewrite the expression in the form 5^n

(5^-8) (5^-10)

Answer 1

Explanation:

This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

Answer 2

5^-18

Explanation:

Law of exponents bases the same add the exponents keep the base.

5^(-8+-10)=5^-18
