$\left(\sqrt[13]{7{x}^{2}y}{\right)}^{3}=\left[\left(7{x}^{2}y{\right)}^{1/13}{\right]}^{3}$ [As$\sqrt[y]{x}={x}^{1/y}$]
$=\left(7{x}^{2}y{\right)}^{\left(1/13\right)\ast 3}$ [As $\left({A}^{x}{\right)}^{y}={A}^{x\ast y}$]
$=\left(7{x}^{2}y{\right)}^{3/13}$
$=\left(7{\right)}^{3/13}\ast \left({x}^{2}{\right)}^{3/13}\ast \left(y{\right)}^{3/13}$
$=\left(7{\right)}^{3/13}\ast \left(x{\right)}^{2\ast 3/13}\ast \left(y{\right)}^{3/13}$
$=\left(7{\right)}^{3/13}\ast \left(x{\right)}^{6/13}\ast \left(y{\right)}^{3/13}$
Answer:- $\left(7{\right)}^{3/13}\ast \left(x{\right)}^{6/13}\ast \left(y{\right)}^{3/13}$
