Answer:

  (c^3-3c^2d+3cd^2-d^3)/c^18

Step-by-step explanation:

It appears you want to simplify ...

  $\left(\dfrac{c^6}{c-d}\right)^{-3}=\left(\dfrac{c-d}{c^6}\right)^3=\boxed{\dfrac{c^3-3c^2d+3cd^2-d^3}{c^{18}}}$

The relevant rule for exponents is ...

  a^-b = 1/a^b

The coefficients of the expansion of the binomial are found in Pascal's triangle.
