One  of the entanglement measure is the concurrence entanglement measure since it is difficult to calculate for an arbitrary mixed state, a series of upper and lower bounds that are easily computable are introduced for it. In this paper using these bounds and also the relation between this measure and the other entanglement measure, called the Renyi entanglement measure, the upper and lower bounds for Renyi entanglement measure are introduced. Then considering a   system, the upper and lower bounds of these two measures and the efficiency of these bounds are investigated.
