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.

Best ResponseYou've already chosen the best response.1\[\frac{2\ln(x)}{x}=0\]doesn't seem too bad.

Best ResponseYou've already chosen the best response.0you 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.

Best ResponseYou've already chosen the best response.0it 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

Best ResponseYou've already chosen the best response.1\[\frac{2\ln(x)}{x}=0,\]\[2\ln(x)=0,\]\[\ln(x)=0,\]\[x=1.\]
