The numerical graph metrics known as topological indices are developed from the molecular graphs of chemical substances. These serve as essential tools for modeling structure-property or structure-activity relationships. The continuous development of novel literature on topological indices highlights their potential uses. we calculated the above topological indices for hexagonal core Dendrimer D3, n-1. Graphs are valuable representations in mathematics. for analyzing a wide variety of real-world situations. Molecular formulas provide a conceptual basis for the computation of topological indices, which are only numerical values.
