What does the Negative Exponent Property say?

141/m^2

Practice makes perfect

To simplify the given exponential expression, we will use the Negative Exponent Property. a^(- n)=1/a^n, for every nonzero numbera and integern Let's try to simplify the given expression using this property.

6/m^2+5m^(-2)/3^(-3)

a^(- m)=1/a^m

6/m^2+5/1/3^3(1/m^2)

a/b/c= a * c/b

6/m^2+5(3^3)/1(1/m^2)
