    In this paper, we obtain α as coefficient for the G = K αn [ K (1 − α)n and by which we discuss Nikiforov s conjecture for λ 1 and Aouchiche and Hansen s conjecture for q 1 in Nordhaus-Gaddum type inequalities. Furthermore, by the properties of the products of graphs we put forward a theory in order to find some bounds of Nordhaus-Gaddum type inequalities.
