The square root of 289 is 17

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.
