Simplify the following expression: (see attachment)
The first step is to make the radical a perfect cube (so that exponent equals index) so as to eliminate the radical from the denominator.
Note: A radical expression of index n is in simplified form if it has:
? no perfect nth powers as factors of the radicand
? no fractions inside the radical
? no radicals in the denominator
I will use the "^" to denote an exponent (the "power" operator)
