The square root of a number X, is the number Y that, when multiplied by itself, gives the number X.
For example, 10 * 10 = 100, so 10 is a square root of 100
Notice that 11 * 11 = 121, so the square root of 120 is close to 11.
Your calculator might have a square root button.

â120
= â(2^2 x 2 x 3 x 5)
= 2â(2 x 3 x 5)
= 2â30
= â(2^2 x 2 x 3 x 5)
= 2â(2 x 3 x 5)
= 2â30
