Square Roots 1

Surds, and other roots

And in general, any number a raised to the power 1 2 equals the square root of a: a1/2 = √ a. So the power, or index, associated with square roots is 1 2. Also, in the same way that the index 1 2 represents the square root, other fractions can be used to represent other roots. The cube root of the number 4 is written as 41/3 = 3 √ 4 where 1 3
