\begin{align*} y^{\prime }&=t^{4} y \end{align*}

Solution by Maple

Time used: 0.001 (sec). Leaf size: 12

dsolve(diff(y(t),t)=t^4*y(t),y(t), singsol=all)
 
\[ y = c_{1} {\mathrm e}^{\frac {t^{5}}{5}} \]

Solution by Mathematica

Time used: 0.022 (sec). Leaf size: 22

DSolve[D[y[t],t]==t^4*y[t],y[t],t,IncludeSingularSolutions -> True]
 
\begin{align*} y(t)\to c_1 e^{\frac {t^5}{5}} \\ y(t)\to 0 \\ \end{align*}
