✓ Maple. Time used: 0.012 (sec). Leaf size: 5

ode:=diff(y(t),t) = y(t)^(1/5); 
ic:=y(0) = 0; 
dsolve([ode,ic],y(t), singsol=all);
 

\[ y = 0 \]

✓ Mathematica. Time used: 0.004 (sec). Leaf size: 24

ode=D[y[t],t]==y[t]^(1/5); 
ic={y[0]==0}; 
DSolve[{ode,ic},y[t],t,IncludeSingularSolutions->True]
 

\[ y(t)\to \frac {4 \sqrt {2} t^{5/4}}{5 \sqrt [4]{5}} \]
