This is about applying the chain rule to a composite function where the outer function is a power and the inner function is a rational expression. Start by treating the fraction as a single unit and bring down the exponent, then multiply by the derivative of that inner fraction using the quotient rule. The key insight is recognizing the layered structure: power on the outside, quotient on the inside—work from outside in.
