Question

differentiate: f(x) = [(5x^4+20x)^3]

Answer 1

We have three terms here:

1)5x^4
2) 20x
3) [5x^4 + 20x]^3

Differentiate each term individually and then put them together.

Answer 2

so then would it be 3(5x^4+20x)^2 * (20x^3+20) * (60x^2)?

Answer 3

How did you getthe 60x^2?

Answer 4

Nvm I thought that you would have to take the deriv of 20x^3, I pretty much thought that it was the argument, thanks a bunch!

Answer 5

We do that in the second derivative.

Answer 6

oh ok gotcha thanks man

Answer 7

No probs bro.
