We show that dust matter-dark energy combined phases can be achieved by the
exact solution derived from a power law $f(R)$ cosmological model. This example
answers the query by which a dust-dominated decelerated phase, before
dark-energy accelerated phase, is needed in order to form large scale
structures.
