Re: binomial thereom

Hi;

By the binomial theorem or Pascals triangle

Now just substitute for a and b


In mathematics, you don't understand things. You just get used to them.

Always satisfy the Prime Directive of getting the right answer above all else.

Re: binomial thereom

hi cooljackiec

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:

Re: binomial thereom

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.


Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
