The study of dynamic equation on measure chain (time scale) goes back to its founder S. Hilger (1988) (Hilger 1988) and is a new area of still fairly theoretical exploration in mathematics. Motivating the subject is the ration that dynamic equation on measure chains can build bridge between continuous and discrete mathematics. It has been created in order to unify the study of differential and difference equations. We also present various properties / several example and application. The study of dynamic inequalities has received a lot of attention in the literature and has become a major field in pure and applied mathematics. In this article we mainly focused on Randons’s Inequality, GronWall’s Inequality, AM-GM Inequality, Lyapunov’s Inequality, Antiderivative and integral and Nesbitts inequality via time scale respectively.
