We study the modified theory of gravity in the Friedmann-Robertson-Walker universe composed of several perfect fluids. We consider the power law inflation and determine the equation of state parameters in terms of the parameters of modified gravity's Lagrangian in the early universe. We also briefly discuss the gravitational baryogenesis in this model.
