Step 1.3

Factor out $x^{3}$ .

$\sqrt[3]{2^{3} \cdot 7 (x^{3} x^{2}) y}$

Step 1.4

Move $7$ .

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

Step 1.5

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

$\sqrt[3]{{(2 x)}^{3} \cdot 7 x^{2} y}$

Step 1.6

Add parentheses.

$\sqrt[3]{{(2 x)}^{3} \cdot 7 (x^{2} y)}$

Step 1.7

Add parentheses.

$\sqrt[3]{{(2 x)}^{3} \cdot (7 x^{2} y)}$

Step 2

Pull terms out from under the radical.

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