Exact : 9 $\sqrt{2}$ $sqrt(2)$ Rounded:~12.728

Explanation:

You can divide $\sqrt{18}$ $sqrt(18)$ into $\sqrt{2 \cdot 9}$ $sqrt(2*9)$ , then simplify that to $\sqrt{2 \cdot 3^{2}}$ $sqrt(2*3^2)$ . Because these 2 terms are multiplicative, the $3^{2}$ $3^2$ can be removed from the square root. The next result would be 3 $\sqrt{2}$ $sqrt(2)$ . Multiply by the previous coefficient term to get 9 $\sqrt{2}$ $sqrt(2)$ . Unfortunately, $\sqrt{2}$ $sqrt(2)$ is irrational so it has no direct decimal conversion, so it must be rounded.

$9 \sqrt{2}$ $9sqrt(2 )$

Explanation:

First, let's figure out how to simplify what's inside.

$\sqrt{18}$ $sqrt(18)$ is the same as $\sqrt{3 \times 3 \times 2}$ $sqrt(3 xx 3 xx 2)$

Circle the pairs. Here you can see their's only one pair and that is of $3$ $3$ . Everything else remains inside. Multiply $3$ $3$ by the $3$ $3$ on the outside and that will get you

$9 \sqrt{2}$ $9sqrt(2)$
