Do you know what a square root is?
If not, here is a definition:
A divisor of a quantity that when squared gives the quantity. For example, the square roots of 25 are 5 and -5 because 5 � 5 = 25 and (-5) � (-5) = 25.

You can substitute a different number for 25.0 to see the square root of another number. The square root of 9 is 3. The square root of 100 is 10.
