Step 1.2.1

Rewrite $16$ as $2^{4}$ .

$3 y^{2} x \sqrt[4]{z} - x \sqrt[4]{2^{4} y^{8} z}$

Step 1.2.2

Rewrite $y^{8}$ as ${(y^{2})}^{4}$ .

$3 y^{2} x \sqrt[4]{z} - x \sqrt[4]{2^{4} {(y^{2})}^{4} z}$

Step 1.2.3

Rewrite $2^{4} {(y^{2})}^{4}$ as ${(2 y^{2})}^{4}$ .

$3 y^{2} x \sqrt[4]{z} - x \sqrt[4]{{(2 y^{2})}^{4} z}$

Step 1.3

Pull terms out from under the radical.

$3 y^{2} x \sqrt[4]{z} - x (2 y^{2} \sqrt[4]{z})$

Step 1.4

Multiply $2$ by $- 1$ .

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

Step 2
