Answer
$4xy\sqrt [3] {y^2}$
Work Step by Step
Rewrite the radicand as the product of factors such that you can take the cube root of certain factors:
$\sqrt [3] {4^3 • x^3 • y^3 • y^2}$
Take the cube roots of terms to take them out from under the radical sign:
$4 • x • y\sqrt [3] {y^2}$
Simplify the radical by multiplying the coefficients:
$4xy\sqrt [3] {y^2}$
