May 9, 2018 · In your case (3 variables), a bit of combinatronics yields: $$ (x+y+z)^n=\sum_{k+l+m=n} \frac{n!}{k!l!m!}x^ky^lz^m $$
- $$(x+y+z)^n=([x+y]+z)^n=\sum_{k=0}^n\binom{n}{k}(x+y)^kz^{n-k}=\sum_{k=0}^n\binom nk\left[\sum_{j=0}^k\binom{k}{j}x^jy^{k-j}\right]z^{n-k}$$
- What you are looking for is the multinomial theorem . In your case (3 variables), a bit of combinatronics yields: $$ (x+y+z)^n=\sum_{k+l+m=n} \frac...
- There is:: $$(x+y+z)^n= \!\!\sum_{\substack{(i,j,k)\in\mathbf N^3\\i+j+k=n}}\!\frac{n!}{i!\,j!\,k!} x^i y^j z^k.$$ It can be extended to sums of mo...
In summary, the conversation starts with the equation x^n + y^n = z^n, which is a general identity for primes and numbers. It then introduces the concepts of multiplication, division, addition, and subtraction, and reminds us to follow the order of operations.

I am interested in the non-trivial integer solutions of $$ x^n + y^n = z^{n-1} $$ for $n \ge 4$. A solution is trivial if $xyz=0$ or $x = \pm y$. There are infinitely many rational solutions to $x^n + y^n = (x+y)^{n-1}$ parametrized in the linked question.
