Simplify first then find the derivative

The video tutorial focuses on simplifying mathematical expressions, particularly dealing with negative exponents. The instructor emphasizes the importance of simplifying expressions as much as possible before applying the power rule. The process involves converting expressions like 3M squared to 9M squared and calculating products such as 6 times 9 to get 54. The key takeaway is the repeated emphasis on the mantra 'simplify, simplify, simplify' before applying any rules.
