Question

What is the derivative of (x^2+1)^x ?

Answer 1

I suggest logrithmig differentiation.

Answer 2

\[y = (x^2+1)^x \]
take the derivative of that bad boy! all of it. even y.

Answer 3

like 1st step will be
\(\log y =\log(x^2+1)^x \\ \log y=x \log(x^2+1)\)
now there is use of product rule and chain rule on right side....
