Question

2x^5-4x^5=

Answer 1

is this a limit question ?

Answer 2

No derivative

Answer 3

10x^4-20x^4

Answer 4

???

Answer 5

ok 2x^5 = 10 x^4

Answer 6

two apples minus 4 apples is minus 2 apples

Answer 7

yes this is right

Answer 8

and so \(2x^5-4x^5 =-2x^5\)

Answer 9

10x^4-20x^4 this would be the answer .. after u take the first derivative

Answer 10

???

Answer 11

f'(x)=10x^4-20x^4
f''(x)= 40x^3-80x^3

Answer 12

right to get the second derivative you take the derivative from the first

Answer 13

I think I understand how to do this. I was just wondering if I was doing it right.

Answer 14

and so on

Answer 15

:)

Answer 16

Thanks. :)

Answer 17

you are welcome ..

Answer 18

i hope this is a joke right?

Answer 19

What is a joke?

Answer 20

\(2x^5-4x^5=-2x^5\)
if you need the derivative or whatever, for the love of pete combine like terms first!!

Answer 21

then the derivative of \(-2x^5=-10x^4\) or whatever you want to do with it

Answer 22

I know that. I was asking if f'(x)=10x^4-20x^4
f''(x)= 40x^3-80x^3 for this function using the product rule.

Answer 23

are the exponents really the same? i am betting there is a typo there

Answer 24

because \(10x^4-20x^4=-10x^4\)

Answer 25

oops maybe that is why I got it wrong! 2x^5-4x^2
Wow I feel really stupid. haha!

Answer 26

whew thank god!!

Answer 27

\[f(x)= 2x^5-4x^2 \]
\[f'(x)=10x^4-8x\]
\[f''(x)=40x^3-8\] and so on

Answer 28

Haha! Wow! Thanks for making me look back at my equation I would have gotten a really easy one wrong! Haha!

Answer 29

yw, i knew it looked goofy, but not as goofy as the answer of taking the derivative piece by piece instead of combining like terms first
