f'(x)=(2 ln(x))/x
How do I find the x value? I put the equation equal to zero, but I do not know any log rule to solve it for x value. I need help please.

That's not possible, unless you're setting f'(x)=0.

\[\frac{2\ln(x)}{x}=0\]doesn't seem too bad.

if you are looking for critical value , look for where function diverge too

what happened if you plug in 0 for x

you can't take the ln(0). There has to be some other way related to log rules to solve this question, and I can't figure it out.

it diverges, which mean it is a criticle point. a critical point of a function of a real variable is any value in the domain where either the function is not differentiable or its derivative is 0

\[\frac{2\ln(x)}{x}=0,\]\[2\ln(x)=0,\]\[\ln(x)=0,\]\[x=1.\]
