Solution by Maple

Time used: 0.001 (sec). Leaf size: 14

dsolve(X^(2/3)*diff(y(x),x) = Y^(2/3),y(x), singsol=all)
 

\[ y \relax (x ) = \frac {Y^{\frac {2}{3}} x}{X^{\frac {2}{3}}}+c_{1} \]

Solution by Mathematica

Time used: 0.003 (sec). Leaf size: 20

DSolve[X^(2/3) y'[x]== Y^(2/3),y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to \frac {x Y^{2/3}}{X^{2/3}}+c_1 \\ \end{align*}
