I mean the derivative of ln(x) is 1/x or if it were 5ln(x) would be 5/x know what I mean?

\[\color{red}{\frac{d}{dx}e^x=e^x.}\]\[\color{blue}{\frac{d}{dx}a^x=a^x \log_e{a}.} \]\[\color{green}{\frac{d}{dx}\log_e{x}=\frac{1}{x}. }\]

Okay I will try to do the proof just give me a second. This is one of those things you really just memorize though like d/dx sin(x) = cos(x) know what I mean? Anyway I will give it a shot.

Wait are you asking me to take the derivative of what you just typed or do you want the proof of ln(x) = 1/x ?

sorry d/dx ln(x) = 1/x I mean

Is this what you just type (x2)/ln(x+2) ? If it is I just do this (x2)*(ln(x+2))^1 then use product rule. So (1/(ln(x+2))) + ((1)(x2)(1/(x+2))(1/(ln(x+2))^2)).

Now are you interested in the proof or?
