May 5, 2018

$18 \sqrt{2}$

#### Explanation:

$15 \sqrt{2}$ is already simplified, but to simplify $\sqrt{18}$ , we need to figure out its factors.

the factors of $18$ are $3 , 3 , \mathmr{and} 2$

$\sqrt{18}$ simplified is $3 \sqrt{2}$

since $3 \sqrt{2}$ and $15 \sqrt{2}$ both have the number $2$ in the root you can add these two radicals to get
$18 \sqrt{2}$
