摘要：

This manuscript is devoted to the investigation of the Bianchi type I universe in the context of f (R, T) gravity. For this purpose, we explore the exact solutions of locally rotationally symmetric Bianchi type I spacetime. The modified field equations are solved by assuming an expansion scalar theta proportional to the shear scalar sigma, which gives A = B-n, where A, B are the metric coefficients and n is an arbitrary constant. In particular, three solutions have been found and physical quantities are calculated in each case.
