Question

Rewrite the expression in the form 5^n (5^-8) (5^-10)

Answer 1

Answer:

5^-18

Step-by-step explanation:

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

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

Answer 2

Answer:

Step-by-step 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.
