Learn how to solve sum rule of differentiation problems step by step online. Find the derivative (d/dx)(e^(8x)+4x+e^(8x)) using the sum rule. Simplifying. The derivative of a sum of two functions is the sum of the derivatives of each function. The derivative of the linear function times a constant, is equal to the constant. The derivative of a function multiplied by a constant (2) is equal to the constant times the derivative of the function.
