%28x%5E3+%2Ay%5E-4%2A+z%5E0%29+%2F+%285x%5E6+%2Ay%5E8%29%5E3............z%5E0+=+1 and y%5E-4+=+1%2Fy%5E4
%28x%5E3+%2A1%2Fy%5E4%2A+1%29+%2F+%285x%5E6+%2Ay%5E8%29%5E3........
Power Theorem for Exponents states %28x%5Em%29%5En+=+x%5Emn
then
%28x%5E3+%2Fy%5E4%29+%2F+%285%5E3%2Ax%5E18+%2Ay%5E24%29........


x%5E3+%2F%28y%5E4+%2A5%5E3x%5E18+%2Ay%5E24%29........

x%5E3+%2F%285%5E3x%5E18+%2Ay%5E28%29........divide by x%5E3 both nominator and denominator

1+%2F%28y%5E4+%2A5%5E3x%5E15+%2Ay%5E24%29........
