Hi guys, I am currently finishing my Calculus 1 course and got stuck in this last exercise. I couldn`t find any similar examples on google and tried to do it in many ways and had no success.

$\displaystyle \text{Let } f(x) = (x^4 + 7)^{ln(x)}$

$\displaystyle \text{Find }f^\prime(x) = $

I dont know what to do. I guess I have to put the ln (x) in front. Ive already tried putting ln in both sides but for some reason its also wrong... What am I suppose to do with the exponent ln (x)?

Thanks guys!
