# How would you simplify sqrt18 times sqrt2?

Aug 3, 2018

$\pm 6$

#### Explanation:

We can move these inside the radical to get

$\sqrt{36}$

We are able to do this because of the radical property

$\sqrt{a} \sqrt{b} = \sqrt{a b}$, assuming $a$ and $b$ are positive.

Knowing this is a perfect square, this easily simplifies to

$\pm 6$
