Question 78759
Think of this in about the same way you would think of finding the least 
common denominator when adding fractions. In this case, you have a square 
root (2) and a cube root (3). If you want to get rid of the radicals, figure out
the smallest number that 2 and 3 go into equally. 
Try that and prove to yourself that it works.

Good Luck,
