Tap for more steps...

Step 1.1

Factor $36$ out of $252$ .

$- \sqrt{36 (7) x^{8} y^{19}}$

Step 1.2

Rewrite $36$ as $6^{2}$ .

$- \sqrt{6^{2} \cdot 7 x^{8} y^{19}}$

Step 1.3

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

$- \sqrt{6^{2} \cdot 7 {(x^{4})}^{2} y^{19}}$

Step 1.4

Factor out $y^{18}$ .

$- \sqrt{6^{2} \cdot 7 {(x^{4})}^{2} (y^{18} y)}$

Step 1.5

Rewrite $y^{18}$ as ${(y^{9})}^{2}$ .

$- \sqrt{6^{2} \cdot 7 {(x^{4})}^{2} ({(y^{9})}^{2} y)}$

Step 1.6

Move $7$ .

$- \sqrt{6^{2} {(x^{4})}^{2} {(y^{9})}^{2} \cdot 7 y}$

Step 1.7

Rewrite $6^{2} {(x^{4})}^{2} {(y^{9})}^{2}$ as ${(6 x^{4} y^{9})}^{2}$ .

$- \sqrt{{(6 x^{4} y^{9})}^{2} \cdot 7 y}$

Step 1.8

Add parentheses.

$- \sqrt{{(6 x^{4} y^{9})}^{2} \cdot (7 y)}$

Step 2

Pull terms out from under the radical.

$- (6 x^{4} y^{9} \sqrt{7 y})$

Step 3

Multiply $6$ by $- 1$ .

$- 6 x^{4} y^{9} \sqrt{7 y}$
