differentiate y=ln(5x^3-4x)?

Answer 1

:-

Let u = 5x³ - 4x

du/dx = 15x² - 4

y = ln u

dy/du = 1/u

dy/dx = (15x² - 4) / u

dy/dx = (15x² - 4 ) / (5x³ - 4x)

Answer 2

When you differentiate the natural log you just get f’(x)/f(x). Take the derivative of whatever’s in your natural log function and put it over what’s in the natural log function.

Answer 3

I'm getting tired of doing your homework!
