simplify %287a%5E-6b%5E-1%29%28a%5E9b%5E0%29
b^0=1
%287a%5E-6%29%28b%5E-1%29%28a%5E9%29
=%287%2Fa%5E6%29%281%2Fb%29%28a%5E9%29
=7a%5E3%2Fb

=%287a%5E-6b%5E-1%29%28a%5E9b%5E0%29
=%287a%5E-6b%5E-1%29%28a%5E9%29 because %28b%5E0%29=1
=%287%2Fa%5E6%29%281%2Fb%29%28a%5E9%29
=%287a%5E9%2Fa%5E6%28b%29%29
=%287cross%28a%5E9%29%2Fcross%28a%5E6%29%28b%29%29
