In this paper, we study the αth power monogamy properties related to the entanglement measure in bipartite states. The monogamy relations related to the αth power of negativity and the Convex-Roof Extended Negativity are obtained for N-qubit states. We also give a tighter bound of hierarchical monogamy inequality for the entanglement of formation. We find that the GHZ state and W state can be used to distinguish both the αth power of the concurrence for 0<α<2 and the αth power of the entanglement of formation for 0<α≤12. Furthermore, we compare concurrence with negativity in terms of monogamy property and investigate the difference between them.
