Abstract:  In this paper‚the existence of the positive solution of the follwing semilinear elliptic equation with critical exponent is studied:
-div(|x|β ∇ u)=|x| α u p-1 +λ|x| σ u q-1 in Ω‚u>0in Ω‚u=0on∂Ω‚
by using Sobolev-Hardy inequality and the Mountain Pass Geometry.

Key words:  semilinear elliptic equation, critical exponent, positive solution, Sobolev-Hardy inequality
