Thanks how about (x*y)^-3= @Luis_Rivera ?

OpenStudy (anonymous):

\[(xy){-3}= \frac{ 1 }{ (xy)^3} \\ =\frac{ 1 }{ \sqrt[3]{xy }}* \frac{ \sqrt[3]{xy } }{ \sqrt[3]{xy }}\\ = \frac{ \sqrt[3]{xy} }{ \sqrt[3]{xy}* \sqrt[3]{xy} }\\ =\frac{ \sqrt[3]{xy} }{ xy }\]

OpenStudy (anonymous):

\[\sqrt[n]{ x^{ 3n}}= \ \ \sqrt{ x ^{3^{n}}}\ \ = x^3\]
