Best ResponseYou've already chosen the best response.1Quotient rule says d/dx(f(x)/g(x)) = (f'(x)g(x)g'(x)f(x))/(g(x))^2 Or more simply, (the derivative of the top times the bottom) minus (the derivative of the bottom times the top) all over the bottom squared. (1/x) = derivative of ln(x) (1/x)(1+ln2x)(1/2x)(lnx)  (1+ln2x)^2

Best ResponseYou've already chosen the best response.1The bottom is just squared, you don't take the derivative of the bottom.

Best ResponseYou've already chosen the best response.1Yeah, you're right the derivative of ln(2x) is 2/2x due to the chain rule, whoops.
