f(x) = e^3 * ln(x)
f'(x)=

Question

f(x) = e^3 * ln(x)
f'(x)=

mimi_x3 · Answer

$$\large f(x) = e^3 * lnx $$
$$\large f”(x) = e^3*\frac{1}{x}   =>\frac{e^{3}}{x}   $$

anonymous · Answer

e^3 is just a constant so....or just look at the answer.

accessdenied · Answer

I'm guessing the equation is
$$y= e^{3 ln(x)} $$
(it seems too easy with just e^3...)

$$ \begin{split}
f(x) &= e^{3ln(x)}\
&= (e^{ln(x)})^{3}\
&=x^{3}\
\end{split}
$$

I think you may want to review some of your Algebra rules for exponents and logarithms!  :)

anonymous · Answer

It's easy either way you look at it.

Yeah, true.  I guess I should rather say, "its more suspicious as (e^3)l(nx).  :P

anonymous · Answer

i definately need some algebra review.

i haven't taken a single math class in 8 years and my school is forcing me to take calculus without allowing me to take the pre-requisites. and i'm trying to graduate this year, so no options but desperately trying to pass

anonymous · Answer

so, i'm going through my book and doing as many problems as i can and every few hours i go online and ask y'all for help

anonymous · Answer

thanks so much for putting up with me all afternoon/night

anonymous · Answer

it's really helped to watch others work out the problems in real time. i've learned a lot from y'all
