simplify using rational exponents.
Assume the problem is
3sqrt%2827x%5E%281%2F2%29%2Ay%5E3%29 * sqrt%284xy%5E%281%2F2%29%29
we can write it:
%2827x%5E%281%2F2%29%2Ay%5E3%29%5E%281%2F3%29 * %284xy%5E%281%2F2%29%29%5E%281%2F2%29
:
%283%2Ax%5E%281%2F6%29%2Ay%29 * %282x%5E%281%2F2%29%2Ay%5E%281%2F4%29%29 = %286%2Ax%5E%28%281%2F6%29%2B%281%2F2%29%29%2Ay%5E%281%2B%281%2F4%29%29%29 =
:
6%2Ax%5E%284%2F6%29%2Ay%5E%285%2F4%29; those exponents are 4/6 and 5/4
