Solution:
To solve the differential equation `(x+ \sqrt(x)) dy/dx = y + \sqrt(y)` by separation of variables, we first need to rewrite it in the form `f(x)dx = g(y)dy`. To do this, we can divide both sides by y
`(x+ \sqrt(x)) dy/y = 1 + \sqrt(y) dx/y`
Now we can separate the variables by moving all the y terms to one side and all the x terms to the other side. This gives us:
`∫(x+ \sqrt(x)) dy = ∫ (1 + \sqrt(y)) dx + C`
Integrating both sides with respect to their respective variables gives:
`x*y + \int\sqrt(x) dy = x + 2*\int\sqrt(y) dy + C`
Solving for y gives:
`y(x+\sqrt(x))=x+2y^(3/2)+C`

So, the general solution is `y(x+\sqrt(x))=x+2y^(3/2)+C` where C is an arbitrary constant.
