In this article, we construct the diquark-diquark-antiquark type interpolating currents, and we study the masses and pole residues of the J(P) = 3/2(-) and 5/2(+) hidden charm pentaquark states in detail with the QCD sum rules by calculating the contributions of the vacuum condensates up to dimension-10 in the operator product expansion. In the calculations, we use the formula mu = root M-Pc(2)
