In the present paper we obtain strong differential superordinations for the differential operator defined as a convex combination of the extended Sălăgean operator and the extended Ruscheweyh derivative, and is the class of normalized analytic functions, the extended Ruscheweyh derivative, the extended Sălăgean operator.
