### Abstract

Recently, Ammar Alsinai et al., [1], introduced Reciprocal leap Zagreb indices of a graph based on the inverse second degree of vertices. The first Reciprocal leap Zagreb index $$RL_{1}(G)$$ is equal to the sum of squares of the inverse second degrees of the vertices, the second Reciprocal leap Zagrab index $$RL_{2}(G)$$ is equal to the sum of the products of the inverse second degrees of pairs of adjacent vertices of $$G$$ and the third Reciprocal leap Zagreb $$RL_{3}$$ is equal to the sum of the products of the inverse first degrees with the inverse second degrees of the vertices. In this paper, exact expression for Reciprocal leap Zagreb indices of wheel $$w_{n}$$, and some related graphs as gear $$G_{n}$$, helm $$H_{n}$$, flower $$fl_{n}$$ and sunflower $$sf_{n}$$ graphs are commuted.
