In this paper, we consider the following elliptic problem:(0.1)− Δ u+ V (x) u+ λ (κ α⁎| u| p)| u| p− 2 u=(κ β⁎| u| q)| u| q− 2 u, x∈ R 3, where λ> 0, 0< α< 3, 0< β< 3, 1+ α 3< p< 3+ α, q> 1 and κ α (x)=| x| α− 3, κ β (x)=| x| β− 3. If V= 1, we show the existence of a ground state solution and multiple solutions, as well as the nonexistence result for (0.1). Furthermore, we investigate the limit behavior of ground state solutions of (0.1) as λ→ 0+. Ground state solutions are also obtained if the potential V is not a constant.
