Question

is the derivative of f(x)=(10)/(3x^3), F'(x)=-10x^2

Answer 1

have you learned the quotient rule?

Answer 2

Yeah, but for this problem it specificly sais not no use it. I gues I could of used it to check my anwere. but i forgot x)

Answer 3

write 10/(3x^3) as 10/3 x^(-3)
then u can take the constant 10/3 and only differentiate x^(-3)
which will be ?

Answer 4

haha or you could do what hartnn says lol im doing implicit differentiation which is pretty fun :)

Answer 5

So... (10/3)(-3x^2)?

Answer 6

nopes,
deribative of x^(-n) = -n x^(-n-1)
n=3 here.
now ?

Answer 7

ohhh! haha my bad x) So it's (10/3)(-3x^-4) . so it reduces to -10x^-4?

Answer 8

yup.

Answer 9

ok! Thanks! Goku has saved the day AGAINNNNN! :D

Answer 10

or -10/x^4

Answer 11

Yup, got it. thanks

Answer 12

welcome ^_^
