I assume you mean 2x%5E5 not 2%5Ex%5E5
%28%28%282x%5E5y%5E-3z%5E4%29%29%2F%28%284%5E0x%5E-2y%5E-8z%5E5%29%29%29%5E3
4^0 = 1 so we can ignore that
%28%28%282x%5E5y%5E-3z%5E4%29%29%2F%28%28x%5E-2y%5E-8z%5E5%29%29%29%5E3
Combine the exponents of like terms in a way to make them positive
= %28%282x%5E7y%5E5%29%2F%28z%5E1%29%29%5E3
Multiply all the exponents by 3
%282%5E3x%5E21y%5E15%29%2F%28z%5E3%29%29 = %288x%5E21y%5E15%29%2F%28z%5E3%29%29
