Question

Answer 1

so using the binomial expansion its

\[^9C_{6} (3c)^{9 - 6}(2a)^6\]

just evaluate

Answer 2

How do I evaluate that?

Answer 3

well \[^9C_{6}\]

is a combination which can be evaluated using a calculator

so you have

\[^9C_{6} \times (3)^3 \times (2)^6 \times(c)^3 \times (d)^6\]

hope this makes it easier
