14) Simplify 4th root of (x^5 divided by 16y^15)
we can write this:
%28%28x%5E5%29%2F%2816y%5E15%29%29%5E%281%2F4%29 = %28x%5E%285%2F4%29%29%2F%2816%5E%281%2F4%29y%5E%2815%2F4%29%29 = %28x%5E%285%2F4%29%29%2F%282y%5E%2815%2F4%29%29

15) Simplify (x1/4 y1/2)2(x2y3)1/2
Assume this means: %28x%5E%281%2F4%29%2Ay%5E%281%2F2%29%29%5E2 * %28x%5E2%2Ay%5E3+%29%5E%281%2F2%29
x%5E%282%2F4%29%2Ay%5E%282%2F2%29 * %28x%5E%282%2F2%29%2Ay%5E%283%2F2%29+%29 = x%5E%281%2F2%29%2Ay * x%2Ay%5E%283%2F2%29+ = x%5E%283%2F2%29%2Ay%5E%285%2F2%29 or sqrt%28x%5E3%2Ay%5E5%29
