For a graph G with k cut edges and a real number say α, we consider the sum, denoted by Ra0(G){R_{alpha}^{0}(G)}, of the αth powers of the degrees of the vertices of G. This sum is also called the zeroth-order general Randić index of the (molecular) graph G. We present some sharp bounds on this sum according to α in different intervals.
