Question

f(x)= 4x^6 ln(x)
find f'(x) and f'(e^2)?
f'(x) will be (24x^5)*ln(x)+(4x^6)*(1/x),
but im confused to derivate if 24x(e^2)^5

Answer 1

you dont have to derive it anymore, insert e^2 for x in f'(x)

Answer 2

f'(x) = (24x^5)*ln(x)+(4x^6)*(1/x)
insert (e^2) for x

so f'(e^2) = (24(e^2)^5)*ln(e^2)+(4(e^2)^6)*(1/(e^2))

Answer 3

oh ya because its written f' (e^2) rite?

Answer 4

yes
