Josh's answers Square Root Defn.**- A square root is a way to find the root of a square. The square root of 9 is 3 because a number (3) x by itself (3) gives you 9. You can also find the square root on a calculator.

You count the amount of #'s between the two perfect squares and make a fraction by subtracting the perfect squares

so the fraction is out of 13. Since 45 is the 9th number the perfect square will be 36 (6x6) and 9/13.
