Abstract

In this paper, we investigate the exact solution of an anisotropic space-time in the context of f(Q)f(Q) gravity, where f(Q)f\left( Q\right) is the arbitrary function of the non-metricity scalar QQ. Here, we consider a specific power-law form as f(Q)=αQn+1+βf\left( Q\right) =\alpha Q^{n+1}+\beta , where α\alpha , β\beta , and nn are free model parameters. Using power-law cosmology (a(t)tma\left( t\right) \propto t^{m}), we analyze the physical behavior of cosmological parameters such as the energy density, pressure, EoS parameter, skewness parameter. Further, we validated the model with energy conditions and found that our f(Q)f\left( Q\right) \ cosmological model behaves like the quintessence model in the present and % \Lambda CDM in the future.
