For measurable functions f of two real variables there are considered the Biikean sums L_m,n∫ of parametric extensions of certain univariate Durrmerer-ivpe operulorsand.The welghted mixed moduli of continuity of_(m,n)f are estimated and the degrees of appraximation of f by_m,nf in some weighted norms are investigated.
