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

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

@technopanda13 thank you!

Haha I was thinking the same thing :D I love that multiply lil astrix XD

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?

baldymcgee6Best ResponseYou've already chosen the best response.1
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...

@baldymcgee6 have a look at the attachment! it's the one labeld problem 10

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?

ohh. sorry, I only saw you're answer :/

@zepdrix i'm glad you like my astrix ;)

simplyfying the answer or u want to know how they r equal

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

baldymcgee6Best 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.

Ah yes logarithmic differentiation is a good skill to have c:

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 \[\ln f(x)=(4x{4}+2)lnx\]
 one year ago

FazeelayazBest 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?
 one year ago

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

@technopanda13 cute kitty! ;P

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

FazeelayazBest ResponseYou've already chosen the best response.0
yes u have done it that's right
