Homework Statement
What is the derivative of ln(2x)?
I was just thinking about this, and I got 2 answers. I am in Calc 2 right now.
Homework Equations
Derivative of ln(x) = 1/x
The Attempt at a Solution
Since d/dx lna = (1/a)*(derivative of a)
Thus d/dx ln2x = (1/2x)*(2)
BUT
I can also do this, I think: d/dx ln2x = 2d/dx lnx = 2*1/x = 2/x
I am CONFUSED! lol !:)
Please tell me which is the correct method! :)
Thanks! :)
