To find \(\frac{dy}{dx}\), we need to differentiate y with respect to x using the chain rule and the power rule of differentiation.
Using the chain rule, we get:
\(\frac{dy}{dx}\) = \(\frac{d}{dx}\)(5 - x)\(^{-3}\)
= -3(5 - x)\(^{-4}\)\(\frac{d}{dx}\)(5 - x)
= -3(5 - x)\(^{-4}\)(-1)
= \(\frac{3}{(5 - x)^4}\)
Therefore, the correct answer is (c) \(\frac{3}{(5 - x)^4}\).
