Properties of Negative Exponents : If $n$ is an integer and $a≠0$, then$a^{-n}=\frac{1}{a^n}or\frac{1}{a^n}=a^n$.

Use the definition of a negative exponent $a^{-n}=\frac{1}{a^n}$, to simplify the given expression.

$r^{-3}=\frac{1}{r^3}$.

Properties of Negative Exponents : If$n$is an integer and$a≠0$, then$a^{-n}=\frac{1}{a^n}or\frac{1}{a^n}=a^n$.

Use the definition of a negative exponent $a^{-n}=\frac{1}{a^n}$, to simplify the given expression.
