Remember the exponential rules and treat them regularly
$x^{-m}=\frac{1}{x^m}$
and
$(x^m)(x^n)=x^{m+n}$
and
$\frac{x^m}{x^n}=x^{m-n}$

that's baseically all you need to know, as long as you understand the rules
here are some examples
$x^{-3}=\frac{1}{x^3}$

$(x^{-4})(x^2)=x^{-4+2}=x^{-2}=\frac{1}{x^2}$

$\frac{x^{-2}}{x^3}=x^{-2-3}=x^{-5}=\frac{1}{x^5}$

Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
