This paper is concerned with the existence of nonoscillatory solutions forthe nonlinear dynamic equation (()(∘)()Δ)Δ+()∘=0 on time scales. By making use of the generalized Riccati transformation technique, weestablish some necessary and sufficient criteria to guarantee the existence. The last examples show that our results can be applied on the differential equations, the difference equations, and the -difference equations
