DSolve[y''[x]*y'''[x] == 2,y[x],x]
Mathematica raw output
{{y[x] -> -1/15*(Sqrt[2]*(2*x + C[1])^(5/2)) + C[2] + x*C[3]}, {y[x] -> (Sqrt[2]
*(2*x + C[1])^(5/2))/15 + C[2] + x*C[3]}}
Maple raw input
dsolve(diff(diff(y(x),x),x)*diff(diff(diff(y(x),x),x),x) = 2, y(x))
Maple raw output
[y(x) = -8/15*(x+_C1)^(5/2)+_C2*x+_C3, y(x) = 8/15*(x+_C1)^(5/2)+_C2*x+_C3]
