Work Step by Step

RECALL: $\dfrac{\sqrt[3]{a}}{\sqrt[3]{b}} = \sqrt[3]{\dfrac{a}{b}}.$ Use the rule above to have $\require{cancel} \sqrt[3]{\dfrac{48x^3y^2}{6x^4y}} \\=\sqrt[3]{\dfrac{\cancel{48}8\cancel{x^3}x^2\cancel{y^2}y}{\cancel{6}\cancel{x^4}x^3\cancel{y}}} \\=\sqrt[3]{\dfrac{8x^2y}{x^3}} \\=\sqrt[3]{\dfrac{2^3x^2y}{x^3}} \\=\dfrac{2}{x} \cdot \sqrt[3]{x^2y} \\=\dfrac{2\sqrt[3]{x^2y}}{x}.$
