Question

I'm stuck on this (Chain Rule!!) Differentiation problem:
\(\ \Huge \frac{1}{(t^4+1)^3} .\)

Answer 1

I would make it a negative exponent.

Answer 2

Can you do it now?

Answer 3

I'll give it a try. Thanks for the hint, @Dido525!

Answer 4

Welcome :) .

Answer 5

Let me know what you get.

Answer 9

SmartScore*

Answer 10

Ohh...

Answer 11

\(\ \large \text{Okay, so I got: }\)
\(\ \Huge -3(t^4+1)^{-4}+4t^3, \)
\(\ \Large\text{Is that correct?} \)

Answer 12

Close, but that is not correct.

Answer 13

@Babyslapmafro \(\ \Large\text{Where did I go wrong?} \)

Answer 14

You must multiply the derivative of the outside by the derivative of the inside, you added the two.

Answer 15

You must multiply not add.
