Question

How do I solve this?

Answer 1

You need 3 of them, since the denominator is a cube root
\[\frac{ \sqrt[3]{5} }{ \sqrt[3]{st^{2}}}*\frac{ \sqrt[3]{st^{2}} }{ \sqrt[3]{st^{2}} }*\frac{ \sqrt[3]{st^{2}} }{ \sqrt[3]{st^{2}} }\]

Answer 2

\[\frac{ \sqrt[3]{5} }{ \sqrt[3]{st^2} }^{(\sqrt[3]{st}}=\frac{ \sqrt[3]{5*st} }{ \sqrt[3]{st^3}}=\frac{ \sqrt[3]{5st} }{ st} \]
