How to find the derivative of a function using the sum and difference rule

The video tutorial covers finding derivatives using the power rule. It begins with rewriting expressions as powers, then explains the application of the power rule. The instructor demonstrates simplifying derivatives without showing full mathematical notation, emphasizing understanding over notation. The tutorial concludes with final simplification steps and clarifies that the derivative of a constant is zero.
