Hey cooljackiec!
You might google "multinomial coefficients" and check out some of the sites to see how to easily
obtain the coefficient of the ab^2c^3 term in (a+2b+3c)^6. I'm guessing that that is where bobbym
got his answer.

The term with c^3 will be
The term in (a+2b)^3 with ab^2 will be
So the coefficient you want will be:
