چكيده فارسي :
Let R be a commutative ring with identity and M an R-module. ##The Scalar Product Graph of M is the graph with M as the vertex set and every edge in this graph is xy such that x = ry or y = rx for some r belong to R . In this paper exact formula for first Zagreb index of Scalarproduct graph of some modules will be presented
