Das (Proc. Camb. Philos. Soc. 67:321-326, 1970) proved that every conservative Hausdorff matrix is absolutely kth power conservative. Savas and Rhoades (Anal. Math. 35: 249-256, 2009) proved the result of Das for double Hausdorff summability. In this paper we will consider the double Endl-Jakimovski (E-J) generalization and we will prove the corresponding result of Sava, s and, Sevas (J. Comput. Anal. Appl. 11:702-710, 2009) for double E-J generalized Hausdorff matrices.
