# How do you find the sqrt289?

Nov 14, 2016

$\setminus \sqrt{289} = \setminus \pm 17$
Depends on if you actually need the $\setminus \pm$ symbol, ask your teacher.

## 1. Use a calculator.

just kidding, I know that'd be too easy...

## 2. Factor out the number under the radical

That's the square root symbol.
$\setminus \sqrt{17 \setminus \times 17}$
Okay... that was fast. I guess your answer is $\setminus \pm 17$, because ${\left(\setminus \pm 17\right)}^{2} = 289$
