1. The problem statement, all variables and given/known data I know how to take the derivative of ln(x), it's just 1/x. But what if you had something more complicated than just x? For example, ln(x4(2x+5)5)? 2. Relevant equations 3. The attempt at a solution I guess you would still do 1/(x4(2x+5)5), then multiply it by the derivative of the denominator. Which would be 4x3(2x+5)5 + x4(5(2x+5)4)(2). Is that correct? The problem I'm supposed to be doing is actually more complicated, it's ln[x5(x+4)3(x3+4)6]. Would the procedure be similar? I guess I'm not sure about taking the derivative of something with 3 terms, I've only ever seen it done with two.
