Popis:	We study Kaluza–Klein space–time in the context of f(R) theory of gravitation in the presence of minimally interacting holographic dark energy. Exact solutions of field equations are obtained for volumetric exponential expansion, power law expansion and hybrid expansion law. Stability of these models is discussed with the help of the square of sound speed relation. The physical parameters of the models are also discussed.
