Radical Expressions/Fractional Exponents

A radical expression may be written as an expression with fractional exponents and vice-versa.
The radical expression  becomes a fractional exponent expression.  Notice the position of the numerator and denominator of the fraction the exponent on the radicand becomes the numerator and the index becomes the denominator.  To reverse the situation, the fractional exponent expression  becomes a radical expression once again, the index becomes the denominator.  The last example can then be further simplified:  .  It would be helpful to review the Rules of Exponents since these rules also apply to expressions with fractional exponents.
