That means that the exponent is a fraction, such as 21/2 = square root of 2, 101/3 = cubic root of 10, etc.

A power with a rational exponent m/n in lowest terms satisfies : whenever this makes sense.
Using a radical (square root) bar. I can't get one on the screen, but I'm sure you know what they look like. Example: fractional exponents can be rewritten in radical form: x2/3 means the cube root of (x2) ... write a radical with an index number 3 to show cube root and the quantity x2 is inside the radical. Any fractional exponent can be done the same way. The denominator of the fractional exponent becomes the index of the radical, but the numerator stays as a whole number exponent in the radical.

The negative exponent is defined as the reciprocal of the positive exponent. Here is an example: 10-2/3 = 1/102/3 This, in turn, can be converted to a root. So, in the end result, you have: 1/102/3 = 1 / cubic root of (102) or 1 / (cubic root of 10)2
