What is the first derivative according to x of the function: f(x)=x^(x)?

Parth (parthkohli):

The first derivative of any function \(\large x^x\) is \(\large x \times x^{x - 1}\)

Parth (parthkohli):

Well that just makes \(\Large x^x\)

OpenStudy (anonymous):

is it \[x^{2+x-1}\]??

Parth (parthkohli):

Nope, it's just \(\large x^x\)

Okay I think for y' = x^x you first need to take the ln of both sides to get lny = lnx^x then because of log properties you can rewrite the right side as lny=xlnx Now I think we do implicit differentiation (1/y)y' = x(1/x)+ln(x) y' = y(1+ln(x)) and we know that y=x^x so y'=x^x(1+ln(x)) or y'= x^x+x^xln(x) and I just checked wolfram and it's right so unless I am misunderstanding the question I am pretty sure Parthkohli is mistaken.
