Step 1.1

Factor $36$ out of $36 x^{2}$ .

$\sqrt{36 (x^{2}) + 36 y^{2}}$

Step 1.2

Factor $36$ out of $36 y^{2}$ .

$\sqrt{36 (x^{2}) + 36 (y^{2})}$

Step 1.3

Factor $36$ out of $36 (x^{2}) + 36 (y^{2})$ .

$\sqrt{36 (x^{2} + y^{2})}$

$\sqrt{36 (x^{2} + y^{2})}$

Step 2

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

$\sqrt{6^{2} (x^{2} + y^{2})}$

Step 3

Pull terms out from under the radical.

$6 \sqrt{x^{2} + y^{2}}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
