Algebra I: Convert between radicals and fractional exponents
 This is a free lesson from our course in Algebra I Here you'll learn how to convert a radical into a fractional exponent. The generalized form of root is given by n x = x1/n. For example, the second root of x is x = x1/2, the third root of x is 3 x = x1/3, and the fourth root of x is  4 x = x1/4. If the fractional exponent has a numerator m( 1), it can be expressed as xm/n = (x1/n)m.
