Best ResponseYou've already chosen the best response.1the log2 is best viewed as ln(x^2+1)/ln(2)

Best ResponseYou've already chosen the best response.1since 1/ln(2) is a constant, all thats left is to consider this as a usual ln(u) type issue

Best ResponseYou've already chosen the best response.0I understand to start by converting the log base 2 into a natural ln base e, which leads to: \[f(x)=x^2(\ln (x^2 + 1) /\ln 2)\] I am unsure how to address the fractional term involving the ln's.

Best ResponseYou've already chosen the best response.0I think the key to this one for me was recognizing that constant.

Best ResponseYou've already chosen the best response.0Would I then use the product rule against the remaining terms x^2 and ln(x^2+1) ?
