Question

I have the answer can someone please check me......
find the derivative of
c(t)=3te^5t

Answer 1

c(t) = 3t* (e^t)^5

use product rule

Answer 2

I got c'(t)=15e^5t+3te^5t
is that correct

Answer 3

i dont think so

Answer 4

What did I do wrong

Answer 5

c'(t) = e^(5t) *3 + 5*e^(4t)*e^t

= 3e^(5t) + 5e^(5t) = 8e^(5t)

Answer 6

I don't have that answer in any of my multiple choice answers

Answer 7

\[c(t) = 3t*e ^{5t}\] is this ur question?

Answer 8

no\[c(t)=3te ^{5t}\]

Answer 9

Is the answer
\[\frac{d}{dt}c(t)=3e^{5t}+15te^5t\]?

Answer 10

Then @agostino is correct

Answer 11

That's what I got.
@Yahoo! You don't reduce the power of the exponential of e.

Answer 12

yes I have that for one of my answers

Answer 13

i found my mistake

Answer 14

c'(t) = 3e^(5t) + 5e^(5t)*3t = 3e^(5t) + 15te^(5t)

Answer 15

ok thanks everyone
