Suppose that the vector x = (x, y, z) has a trinomial distribution depending on the index

Question:

Suppose that the vector x = (x, y, z) has a trinomial distribution depending on the index n and the parameter π = (π , p, σ), where π + p + σ = 1, that is

p(x|) n! x!y!z! -*p (x+y+z= n).

Show that this distribution is in the two-parameter exponential family.
