Oh,I think I get it. We divide by the factorial of the exponent because that is a case when we take "the exponent" number of that letter so we need to divide by "the exponent" factorial.

Try this one then:

"Murmur", 5 letters.

Hi bobbym

The number of letters really doesn't matter when we are looking for a GF.

Are you sure?

"MURMURING", create a generating function that counts all possible arrangements of n letters.

That is very good!

Now how do we get the number of ways for 8 letters out of that?

Taking a break.

I have the result, but I do not yet know how to get it.

We take the coefficient with x^8.

Ok,see you later!

I am not sure if it is 9 or 9!/8 or neither.

The coefficient of x^8 is then multiplied by 8!.

Hi;

You gave a couple of answers. The closest had a maybe in it. You have to post your answer and stand by it.

I thought you were saying that was the coefficient of x^8. Please be a bit more explanatory in your answers. That will prevent misunderstandings. Had you labelled that the final answer or the no of ways then it would have been clear to me.
