$x \sqrt{y^{3}} + \sqrt{x^{2} y^{5}} - 5 x \sqrt{y^{7}}$

Step 1

Factor out $y^{2}$ .

$x \sqrt{y^{2} y} + \sqrt{x^{2} y^{5}} - 5 x \sqrt{y^{7}}$

Step 2

Pull terms out from under the radical.

$x (y \sqrt{y}) + \sqrt{x^{2} y^{5}} - 5 x \sqrt{y^{7}}$

Step 3

Rewrite $x^{2} y^{5}$ as ${(x y^{2})}^{2} y$ .
