\[ \boxed {{y^{\prime }}^{2}=x^{6}} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 21

dsolve(diff(y(x),x)^2=x^6,y(x), singsol=all)
 

\begin{align*} y \left (x \right ) &= \frac {x^{4}}{4}+c_{1} \\ y \left (x \right ) &= -\frac {x^{4}}{4}+c_{1} \\ \end{align*}

Solution by Mathematica

Time used: 0.004 (sec). Leaf size: 29

DSolve[(y'[x])^2==x^6,y[x],x,IncludeSingularSolutions -> True]
                                                                                    
                                                                                    
 

\begin{align*} y(x)\to -\frac {x^4}{4}+c_1 \\ y(x)\to \frac {x^4}{4}+c_1 \\ \end{align*}
