Hi

I need to find the derivative of the following

y=(4sqrtx)^lnx

Ummmm, so I'm not really sure how to type that. It is the ("forth root" of x) to the power of (lnx).

I thought that maybe you could change it to

y=x^(.25lnx)

lny=ln.25lnxlnx

lny=ln.25(lnx)^2

(1/y)(y')=f'g+fg'

(1/y)(y')=(0(lnx))+(ln.25)(2(lnx)(1/x))

y'=[(2(ln.25)(lnx))/x]((4sqrtx)^lnx)

Is this assumption incorrect?
