Let G be a simple graph of order n. The energy E(G) of the graph G is
the sum of the absolute values of the eigenvalues of G. The Randi\'{c} matrix
of G, denoted by R(G), is defined as the n×n matrix whose
(i,j)-entry is (di​dj​)2−1​ if vi​ and vj​ are adjacent and
0 for another cases. The Randi\'{c} energy RE of G is the sum of absolute
values of the eigenvalues of R(G). In this paper we compute the energy and
Randi\'{c} energy for certain graphs. Also we propose a conjecture on Randi\'c
energy.Comment: 14 page
