Abstract: In this paper we propose the q analogues of modified Baskakov-Sz′asz operators.we estimate the moments and establish the direct results in term of modulus of continuity.An estimate for the rate of convergence and weighted approximation properties of the q operators are also obtained. 

Key words: q-Sz\acute{a}sz-Mirakyan-Baskakov operators, q-analogues, modulus of continuity; weighted approximation
