In this paper we discuss the efficiency of the g -expansion method to construct the exact solutionsof the nonlinear time-fractional equations. This method is considered for application to the spacetimefractional Burgers-Huxley equation. These solutions are benefit to further understand theconcepts of the complicated nonlinear physical phenomena and fractional differential equations. Inthis study we use of Mathematica for computations and programming
