Graph theory has provided a very useful tool, called topological indices which are a number obtained from the graph G with the property that every graph H isomorphic to G, value of a topological index must be same for both G and H. In this article, we present exact expressions for some topological indices of k-th subdivision graph and semi total point graphs respectively, which are a generalization of ordinary subdivision and semi total graph for k> 1.
