# How do I find the derivative of #f(x)=(16x^2+1) ln (x-3)#?

##### 1 Answer

This question will demand the use of chain rule and product rule, as well as the knowledge of how to derivate a logarithmic function.

#### Explanation:

First of all, we have a product of two terms:

#16x^2+1# #ln(x-3)#

However, one cannot derivate straightforward a logarithmic function with a function in it. Instead, we must apply chain rule and rename

Fine. Now, we can apply the product rule, which states that, for

(where the symbol

The struggle to develop and try to simplify it is not worth it. This is your final answer!
