(a^-9b^-9)(a^3b^-8)I* geta^3/ a^9b^17 which I simpliified to 1/a^6b^17 am I close??1 more 1/(8xy^-6)^-1 where I get8xy^6???Checking my freshman sons homework and he gets something total different......help please:/
(a^-9*b^-9)(a^3*b^-8)= (1/a^9)(1/b^9)(a^3)(1/b^8)= 1/(a^6*b^17)1/(8xy^-6)^-1 = 1 / (y^6/8x)= 8x/y^6
