In this paper, we study the uniqueness of meromorphic functions and prove the following result: Let be a positive integer, , and let and be two nonconstant meromorphic functions whose poles are of multiplicities at least 2. If , , and , then . This result also answer a question of Gross [4] and improve some results of Fang and Xu [1], Yi [14] and Yi [15].
