%28a%5E%28-2%29b%5E5%29%5E%28-8%29
The exponents here are -2 , 5 and -8. Of those three exponents, two are negative and one is positive. You need to know that a%5E%28-b%29+=+1%2F%28a%5Eb%29
Use this rule o f exponents to solve the given equation.
%28a%5E%28-2%29b%5E5%29%5E%28-8%29
a%5E16b%5E%28-40%29
a%5E16%2Fb%5E40
