How do you do fractional and negative exponents such as (2m^0 n^4)4 over m^-2 n^-4•2m^0 n^3
--------------
Is that last 4 in the NUM an exponent? If so,
%28%282m%5E0%2An%5E4%29%5E4%29%2F%28m%5E-2%2An%5E-4%2A2m%5E0%2An%5E3%29
Cancel anything ^0. it's = 1
= %28%282n%5E4%29%5E4%29%2F%28m%5E-2%2An%5E-4%2A2n%5E3%29
= 16n%5E16%2F%28m%5E-2%2An%5E-4%2A2n%5E3%29
= 16n%5E16%2F%282m%5E-2%2An%5E-1%29
Multiply NUM and DEN by n
= 16n%5E17%2F%282m%5E-2%29
Multiply NUM and DEN by m^2
= 16m%5E2n%5E17%2F2
= 8m%5E2n%5E17
