I'm not sure if i did it right and i'm not sure where it's going?

alright... i think i get it, but i don't get how or why the x becomes and e?

Hmm your steps look really good. I don't see any mistakes. For your final answer I would rewrite the ugly exponential term back as x^(4x^4 + 2), The one in front.

Oh need an explanation on the exponentiation + log thing?

Yeah, it looks good to me too. But where did the e and the natural log all the sudden appear from?

it was part of the hint...but i'm not sure why it works that way...

X^(x2+2) is same as e^(4x2+2)lnx u can use calculator to verify

@Fazeelayaz alright, but how would i go about simplifying it?

@zepdrix great explanation! I understand it now! But how to simplify?

@PoofyPenguin the reason they give you that hint is to avoid logarithmic differentiation. But for future derivatives, I would recommend learning log diffs. This is just a loophole around it! But good work, it looks good to me.

What you have written for f'(x) is perfect poof, you just want to rewrite the first part without the e and natural log, undo your FIRST step that you did to it.

o i understand there is another way to solve take ln on both sides of ur question the equation becomes \[\ln f(x)=(4x{4}+2)lnx\]
 2 years ago

Fazeelayaz Group TitleBest ResponseYou've already chosen the best response.0
now differentiate both sides by x

alright! so would this be the final answer or can it be simplified more?

\[1/f(x)*(df(x)/dx)=...\]use product rule on left side

You could get a common denominator on the inside if you wanted to, but it totally unnecessary c: Yah it looks good there.
