%28-3ab%5E7%29%5E3%28a%5E-4%29%28b%5E2%29%2Fb%5E-5
%28-3%29%5E3%2Aa%5E3%2A%28b%5E7%29%5E3%2Aa%5E%28-4%29%2Ab%5E2%2Fb%5E-5
-27%2Aa%5E3%2Ab%5E21%2Aa%5E%28-4%29%2Ab%5E2%2Fb%5E-5
reordering
-27%2Aa%5E3%2Aa%5E%28-4%29%2Ab%5E21%2Ab%5E2%2Fb%5E-5
-27%2Aa%5E%28-1%29%2Ab%5E23%2Fb%5E-5
a^-1 shift to bottom b^5 to top
-27%2Ab%5E23%2Ab%5E5%2Fa%5E1
-27%2Ab%5E28%2Fa
