    :-

    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)

  • 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.
