### Abstract

In this paper, using Laplace transform technique, we propose the generalized solutions of the fourth order Euler differential equations $t^4y^{(4)}(t)+t^3y'''(t)+t^2y''(t)+ty'(t)+my(t)=0,$ where $m$ is an integer and $t\in\mathbb{R}$. We find types of solutions depend on the values of $m$. Precisely, we have a distributional solution for $m=-k^4-5k^3-9k^2-4k$ and a weak solution for $m=-k^4+5k^3-9k^2+4k,$ where $k\in\mathbb{N}.$
