You can put this solution on YOUR website!
(4 x-3 y5 z-2 over 6 y-5 z5 x-8) -2
I think you mean exponents.
Use ^, Shift 6, for exponents.

%28%284x%5E-3y%5E5z%5E-2%29%2F%286y%5E-5z%5E5x%5E-8%29%29%5E-2
Put in x,y,x order, divide NUM & DEN by 2
= %28%282x%5E-3y%5E5z%5E-2%29%2F%283x%5E-8y%5E-5z%5E5%29%29%5E-2
= 1%2F%28%282x%5E-3y%5E5z%5E-2%29%2F%283x%5E-8y%5E-5z%5E5%29%29%5E2
Invert, change -2 to +2
= %28%283x%5E-8y%5E-5z%5E5%29%2F%282x%5E-3y%5E5z%5E-2%29%29%5E2
Multiply NUM & DEN by x^8
= %28%283y%5E-5z%5E5%29%2F%282x%5E5y%5E5z%5E-2%29%29%5E2
Multiply NUM & DEN by y^5
= %28%283z%5E5%29%2F%282x%5E5y%5E10z%5E-2%29%29%5E2
Multiply NUM & DEN by z^2
= %28%283z%5E7%29%2F%282x%5E5y%5E10%29%29%5E2
Square NUM and DEN
= 9z%5E14%2F%284x%5E10y%5E20%29
