May 18, 2018

The square root of 289 is 17

Explanation:

So let put 289 in the house.

$\sqrt{289}$

So the doorbell is literally a 2 unless it states otherwise. So this is asking us what number times itself gives us 289.

So when we plug $\sqrt{289}$ into our calculator, we get 17. But do we know if it correct?

Let square 17.

${17}^{2}$ = $289$

So we know this work or we could of #17*17=289.

Either way of checking to ensure 17 is our final answer is alright.
