Question

Find the derivative of the function.
f(x) = 3x2 ln(8x)

Answer 1

use product rule and chain rule
f(x)=3x, g(h(x)) = 2ln(h), h(x) = 8x
chain rule: g(x)' = h(x)'g(h)'
product rule: fg(x)' = f'g + fg'

Answer 2

the problem got typed in wrong it should say
3x^2 ln(8x)

Answer 3

ok sorry just change the functions accordingly same steps though

Answer 4

im still confused about wat u did

Answer 5

ok just split it into two parts
3x^2ln(8x) = (3x^2)*(ln(8x))
Now think of it as two different functions multiplied together

Answer 6

then apply the product rule
call one function f and the other g
(f*g)' = f'g +g'f
