At its most fundamental, a fractional exponent is an alternative way to write a radical expression. For any base and a positive integer , the expression b1/nb raised to the 1 / n power is defined as the th root of
When $n$ is even, $a$ must be greater than or equal to 0 to yield a real number result (unless we are venturing into complex numbers, which Algebra II typically avoids until later). Fractional Exponents Revisited Common Core Algebra Ii
