Question 174824
Simplify each expression write answer using positive exponents. 

(-3cd^2)^3(c^-1 d^-3)^3
_______________________
(c^3d)^5
-----------------
{{{((-3cd^2)^3(c^-1d^-3)^3)/(c^3d)^5}}}  Expand everything
={{{((-27c^3d^6)(c^-3d^-9))/c^15d^5}}}  Cancel c^3 and c^-3
={{{((-27d^6)*(d^-9))/c^15d^5}}} Combine d^6 and d^-9
={{{((-27d^-3))/c^15d^5}}} Move d^-3 to DEN
={{{(-27)/c^15d^8}}}
