Answer

$\frac{3x \sqrt[3]{2x}}{7y^2}$

Work Step by Step

The given expression is $=\sqrt[3]{\frac{54x^4}{343y^6}}$ Factor as cube terms. $=\sqrt[3]{\frac{27x^3\cdot 2x}{343(y^2)^3}}$ Use quotient property of cube roots. $=\frac{\sqrt[3]{27x^3\cdot 2x}}{\sqrt[3]{343(y^2)^3}}$ Use product property of cube roots. $=\frac{\sqrt[3]{27}\sqrt[3]{x^3} \sqrt[3]{2x}}{\sqrt[3]{343}\sqrt[3]{(y^2)^3}}$ Simplify. $=\frac{3x \sqrt[3]{2x}}{7y^2}$.
