\[ \left \{ {\frac {y \left ( x \right ) }{{x}^{a}x}}+{\frac {1}{{x}^{a}x}\sqrt { \left ( y \left ( x \right ) \right ) ^{2}+{b}^{2}{x}^{2}}}-{\it \_C1}=0 \right \} \] Mathematica raw input
DSolve[x*y'[x] == y[x] + a*Sqrt[b^2*x^2 + y[x]^2],y[x],x]
Mathematica raw output
{{y[x] -> -(b^2*x^(1 - a))/(2*E^C[1]) + (E^C[1]*x^(1 + a))/2}}
Maple raw input
dsolve(x*diff(y(x),x) = y(x)+a*(y(x)^2+b^2*x^2)^(1/2), y(x),'implicit')
Maple raw output
1/(x^a)/x*y(x)+1/(x^a)/x*(y(x)^2+b^2*x^2)^(1/2)-_C1 = 0
