Question

What is the square root of 144?

Answer 1

To find the square root, think of number that can be multiplied together to get to 144.

First, try 10 * 10. That equals 100, which is a too small.
Try something larger like 13! 13 * 13 = $169$, which is close, but not 144 exactly.
Let's try 12... 12 * 12 = 144. That works!

Thus, the square root of 144 is 12. 
I hope that helps!
