Final answer to the problem
Step-by-step Solution
Learn how to solve sum rule of differentiation problems step by step online. Find the derivative of ln(x-5). The derivative of the natural logarithm of a function is equal to the derivative of the function divided by that function. If f(x)=ln\:a (where a is a function of x), then \displaystyle f'(x)=\frac{a'}{a}. The derivative of a sum of two or more functions is the sum of the derivatives of each function.
