anonymous 5 years ago Differentiate the given function: lnx^3 should the next step be 3lnx^2
1. apples
Well, note that here you would use the chain function. The outer function is log(x) and the inner function is x^3. Noting that $\frac{d}{dx} \left(f(g(x))\right) = f'(g(x)) \cdot g'(x)$ then you'll want to different... | {} |
