Abstract
We consider Noether symmetry approach to find out exact cosmological solutions in -gravity. Instead of taking into account phenomenological models, we apply the Noether symmetry to the gravity. As a result, the presence of such symmetries selects viable models and allow to solve the equations of motion. We show that the generated leads to a power law expansion for the cosmological scale factor.
