In this paper, we consider the spectral problem of the form:

Where λ is a spectral parameter in which λ=σ+iδ, where

; p
3(x), p
4(x) and ρ(x) are real valued functions and we assume that ρ(x)>0, p
4(x)∈C[0,a], p
3(x)∈C
2[0,a] and ρ(x)∈C
4[0,a]. Asymptotic formulas for eigenvalues and solutions of the consider boundary value problem are established.
