Question

find dy/dx of y = x^3e^x Click to see my work. I can't figure out what to do next. simplify?

Answer 1

dy/dx = (x^3)(e^x) + (e^x)(3x^2)

Answer 2

is it already simplified?

Answer 3

sorry got caught up with something is this the original?

Answer 4

\[x ^{3}e ^{e}\]

Answer 5

yes!

Answer 6

thank you for helping me again :)

Answer 7

then your wrong lol. e^e is just a number just treat like if it was a 3 or 4 or something

Answer 8

you only take the derivative of something if it has an variable in it like x for example

Answer 9

oh wait! it is e^x, not e^e

Answer 10

oh then in that case

Answer 11

your right

Answer 12

i don't think it can be further simplified

Answer 13

right?

Answer 14

you can factor our an e^x to simplify but that's about it.

Answer 15

so: e^x((x^3 + 3x^2)) ?

Answer 16

yea that's about all you can do. again if you don't need to simplify don't

Answer 17

i'm not sure if i do. but it's just easier for me to understand it simplified. thanks so much!! on to the next question... :(
