Question

differentiate 3xe^x+4e^x

Answer 1

might as well factor them and have only one product rule.

Answer 2

so y= e^(x) [ 3x+4]

Answer 3

dang it, i was wrong =[ Thank you

use the sum rule.

Answer 5

\[\frac{dy}{dx} = e^{x} ( \frac{d}{dx} (3x+4)) + (3x+4) \frac{d}{dx}(e^{x})\]

Answer 6

so u just take the e^x out

Answer 7

because derivitive of e^x is e^x

Answer 8

\[= 3e^{x} + e^{x} [ (3x+4)] = 3xe^{x} +7e^{x}\]

Answer 9

I factored it first, then did product rule on the whole expression.

Answer 10

ahh

Answer 11

calculus is ALL about putting it into relative workable chunks right elec? pretty easy once you get the hang of it.. all it takes is just seeing it. :D

Answer 12

true, true
