Find the derivative using the power rule

The video tutorial explains how to simplify expressions and apply the power rule to find derivatives. It starts with rewriting terms to make them easier to differentiate, then demonstrates the application of the power rule to derive the final expression. The process involves converting terms to a suitable form for differentiation and simplifying the result.

Explain how the negative exponent is converted to a normal power.

What is the result of applying the power rule to the expression mentioned?
