Question

Rewrite using a negative exponent 1/(xy)^1

Answer 1

apply the exponent rule: a^-1=1-a
(xy)^-1=1/xy
Apply the fraction rule: 1/b/c=c/b
apply rule a/1=a
=xy

Answer 2

`\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)} \\\\ -------------------------------\\\\\cfrac{1}{(xy)^1}\implies (xy)^(-1)`
