Perhaps the questions are auto generated and the problem could lie in the auto generation... Mar 1 comment Derivative chainrule on khanacadamy ignoring some terms @Gibarian thanks for the idea. I've submitted an "report an error" to khan academy with an a link to this page. Mar 1 awarded Supporter Mar 1 comment Derivative chainrule on khanacadamy ignoring some terms Babak S. Why would they ignore terms? Are the terms somehow insignificant?

I can see two types of approach one using logarithms and the other is just using exponents... which is more correct ?
