Question

the expression ((x^2y^-5z^-4)/((xy)^-3z^4)))^-1 find x^r y^s z^t

Answer 1

those two are one question?

Answer 2

\[((x^2y^{-5} z^{-4})/((xy)^{-3}z^4))^{-1}\]

Answer 3

equals x^r y^s z^t, find r,s,t

Answer 4

\[\left(\begin{matrix}x^2y ^{-5}z ^{-4} \\ (xy)^{-3}z^4\end{matrix}\right)^{-1}\]
