Tap for more steps…

Move $w$ .

$6 w \sqrt{2 z a^{2} w} - a \sqrt{18 w^{3}}$

Move $z$ .

$6 w \sqrt{2 a^{2} z w} - a \sqrt{18 w^{3}}$

Reorder $2$ and $a^{2}$ .

$6 w \sqrt{a^{2} \cdot 2 z w} - a \sqrt{18 w^{3}}$

Add parentheses.

$6 w \sqrt{a^{2} \cdot 2 (z w)} - a \sqrt{18 w^{3}}$

Add parentheses.

$6 w \sqrt{a^{2} \cdot (2 z w)} - a \sqrt{18 w^{3}}$

Pull terms out from under the radical.

$6 w (a \sqrt{2 z w}) - a \sqrt{18 w^{3}}$

Rewrite $18 w^{3}$ as ${(3 w)}^{2} \cdot (2 w)$ .

Tap for more steps…

Factor $9$ out of $18$ .

$6 w a \sqrt{2 z w} - a \sqrt{9 (2) w^{3}}$

Rewrite $9$ as $3^{2}$ .

$6 w a \sqrt{2 z w} - a \sqrt{3^{2} \cdot 2 w^{3}}$

Factor out $w^{2}$ .

$6 w a \sqrt{2 z w} - a \sqrt{3^{2} \cdot 2 (w^{2} w)}$

Move $2$ .

$6 w a \sqrt{2 z w} - a \sqrt{3^{2} w^{2} \cdot 2 w}$

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

$6 w a \sqrt{2 z w} - a \sqrt{{(3 w)}^{2} \cdot 2 w}$

Add parentheses.

$6 w a \sqrt{2 z w} - a \sqrt{{(3 w)}^{2} \cdot (2 w)}$

Pull terms out from under the radical.

$6 w a \sqrt{2 z w} - a (3 w \sqrt{2 w})$

Multiply $3$ by $- 1$ .

$6 w a \sqrt{2 z w} - 3 a w \sqrt{2 w}$

Simplify 6w square root of 2zwa^2-a square root of 18w^3
