Find number of dissimilar terms in the expansion where p,q,r are different integers and n is a non-negative integers.(p,q,r may be either positive or negative and a,b,c are any real numbers)
Does there exist a general formula?

for the expansion of (t1+t2+...+tm-1+tm)^n there are
(n+m-1)!/(n!*(m-1)!) terms as long as p, q, r do not equal 0. if so then simplify the expression and repeat this procedure from the beginning
i am famaliar with this formula.but does it work in this case.For e.g. in expansion of there are dissimilar terms.
