I'm having some trouble with this problem

can i separate it into dy/dx=(8y)(ln(x))(1/x) or am I approaching it wrong?

this is what I got when I tried it

thanks

$\frac{dy}{y} = \frac{8\ln{x}}{x} \, dx$

$\ln|y| = 4\left(\ln{x}\right)^2 + C$

note where the square is on the right side.

3. I agree with your answer.

Got it, was just needed to take out the abs value on the right side, thanks
