Best ResponseYou've already chosen the best response.0I'm not sure if i did it right and i'm not sure where it's going?

Best ResponseYou've already chosen the best response.0alright... i think i get it, but i don't get how or why the x becomes and e?

Best ResponseYou've already chosen the best response.2Hmm 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.

Best ResponseYou've already chosen the best response.2Oh need an explanation on the exponentiation + log thing?

Best ResponseYou've already chosen the best response.1Yeah, it looks good to me too. But where did the e and the natural log all the sudden appear from?

Best ResponseYou've already chosen the best response.0it was part of the hint...but i'm not sure why it works that way...

Best ResponseYou've already chosen the best response.0@baldymcgee6 have a look at the attachment! it's the one labeld problem 10

Best ResponseYou've already chosen the best response.0X^(x2+2) is same as e^(4x2+2)lnx u can use calculator to verify

Best ResponseYou've already chosen the best response.0@Fazeelayaz alright, but how would i go about simplifying it?

Best ResponseYou've already chosen the best response.0@zepdrix great explanation! I understand it now! But how to simplify?

Best ResponseYou've already chosen the best response.1@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.

Best ResponseYou've already chosen the best response.2Ah yes logarithmic differentiation is a good skill to have c:

Best ResponseYou've already chosen the best response.2What 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.

Best ResponseYou've already chosen the best response.0o i understand there is another way to solve take ln on both sides of ur question the equation becomes \[\ln f(x)=(4x{4}+2)lnx\]

Fazeelayaz

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

Best ResponseYou've already chosen the best response.0alright! so would this be the final answer or can it be simplified more?

Best ResponseYou've already chosen the best response.0\[1/f(x)*(df(x)/dx)=...\]use product rule on left side

Best ResponseYou've already chosen the best response.2You could get a common denominator on the inside if you wanted to, but it totally unnecessary c: Yah it looks good there.
