PART 2

Another way to write a radical is as a rational (or fractional) exponent. For example,

another way to write  is  x^3/2. The numerator of the rational exponent is the exponent on the variable and the denominator of the rational exponent is the index of the radical.

Example 1.         

                           Remember, the index of a square root is a 2.

Example 2.         

                           Remember, when you don’t see an exponent, the exponent is a 1.
