Step 1.4

Move $x$ .

$\sqrt[3]{2 x y^{2}} + \sqrt[3]{2^{3} \cdot 2 y^{3} x y^{2}} + \sqrt[3]{2 x^{4} y^{2}}$

Step 1.5

Move $2$ .

$\sqrt[3]{2 x y^{2}} + \sqrt[3]{2^{3} y^{3} \cdot 2 x y^{2}} + \sqrt[3]{2 x^{4} y^{2}}$

Step 1.6

Rewrite $2^{3} y^{3}$ as ${(2 y)}^{3}$ .

$\sqrt[3]{2 x y^{2}} + \sqrt[3]{{(2 y)}^{3} \cdot 2 x y^{2}} + \sqrt[3]{2 x^{4} y^{2}}$

Step 1.7

Add parentheses.

$\sqrt[3]{2 x y^{2}} + \sqrt[3]{{(2 y)}^{3} \cdot 2 (x y^{2})} + \sqrt[3]{2 x^{4} y^{2}}$

Step 1.8

Add parentheses.

$\sqrt[3]{2 x y^{2}} + \sqrt[3]{{(2 y)}^{3} \cdot (2 x y^{2})} + \sqrt[3]{2 x^{4} y^{2}}$

Step 2

Pull terms out from under the radical.

$\sqrt[3]{2 x y^{2}} + 2 y \sqrt[3]{2 x y^{2}} + \sqrt[3]{2 x^{4} y^{2}}$
