CAS Maple gives this as type [_separable]

\[ \boxed {y^{\prime }-t y^{\frac {1}{3}}=0} \]

Solution by Maple

Time used: 0.015 (sec). Leaf size: 16

dsolve(diff(y(t),t)=t*y(t)^(1/3),y(t), singsol=all)
 

\[ y \left (t \right )^{\frac {2}{3}}-\frac {t^{2}}{3}-c_{1} = 0 \]

Solution by Mathematica

Time used: 0.346 (sec). Leaf size: 31

DSolve[y'[t]==t*y[t]^(1/3),y[t],t,IncludeSingularSolutions -> True]
 

\begin{align*} y(t)\to \frac {\left (t^2+2 c_1\right ){}^{3/2}}{3 \sqrt {3}} y(t)\to 0 \end{align*}
