In 2019, a new labeling called Product Root Sum Mean Labeling was introduced in the literature. It is defined in a graph G=(p,q) as an injective function f: V →7{1,2,3,...,q+1} such that the induced function f~* defined by f~*(uv)=f(u)~*f(v)+(f(u)+f(v))~(1/2)/2 yield different values on edges. A paper which admits this labeling is known as Product Root Sum Mean graph. In this paper we prove that the ladder graph, the Square Ladder graph, the cocunut tree CT(m,m), the graph Y_(r+1), the Star graph K_(1,n), the Shadow graph of Star K_(1,n), the Split graph of Star K_(1,n), the BiStar graph K_(n,n), the Shadow graph of BiStar K_(n,n), the Comb graph P_n⊙K_1, the Square graph of Comb Pn⊙K_1, the Shadow graph of Comb D_2(Pn⊙K_1) and the splitting graph of Comb are Product Root Sum Mean graphs.
