Practice makes perfect

We want to evaluate the given exponential expression. 1/5^(- 3) * 1/5^6 We will use the Product of Powers Property. This property states that when multiplying two exponential expressions] with the same base, we add the exponents.

1/5^(- 3)* 1/5^6

Multiply fractions

1/5^(- 3)* 5^6

a^m*a^n=a^(m+n)
