$\bf ~~~~~~~~~~~~\textit{negative exponents}

a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}

$\bf \textit{area of a rectangle}\\\\
A=WL~~
\begin{cases}
W=width\\
L=length\\
-----\\
A=24a^2b\\
L=8ab^2
\end{cases}\implies 24a^2b=W(8ab^2)\implies \cfrac{24a^2b}{8ab^2}=W
\\\\\\
\cfrac{24}{8}\cdot \cfrac{a^2b}{ab^2}=W\implies 3\cdot \cfrac{a^2a^{-1}}{b^2b^{-1}}=W\implies 3\cdot \cfrac{a^{2-1}}{b^{2-1}}=W\implies \cfrac{3a}{b}=W$
