Abstract: In this paper,the meromorphic solution to Fermat type functional equations is investigated.We prove that there do not exist non-constant meromorphic functions f(z),f(s)(z)and h(z)with order less than one that satisfy the functional equation f(z)7+f(s)(z)7+h(z)7 =1.

Key words: Fermat type functional equation, Meromorphic functions , Nevanlinna theory
