In this study, the value distribution of the differential polynomial
is considered, where f
is a transcendental meromorphic function,
is a small function of f
by the reduced counting function. This result improves the existed theorems which obtained by Jiang (Bull Korean Math Soc 53: 365-371, 2016) and also give a quantitative inequality of
