Question
**Polynomial Differentiation Exercise**

Let \( p \) be an arbitrary polynomial defined as:

\[ p(x) = a_n x^n + a_{n-1} x^{n-1} + \cdots + a_1 x + a_0, \, a_n \neq 0. \]

**Questions:**

(a) Find \(\frac{d^n}{dx^n}[p(x)]\).

(b) What is \(\frac{d^k}{dx^k}[p(x)]\) for \(k > n\)?

**Explanation:**

To solve these differentiation problems, consider the order of derivatives:

- For part (a), calculating the \(n\)-th derivative of a polynomial will reduce it to a constant if it is of degree \(n\).

- For part (b), any derivative of order greater than \(n\) of a polynomial of degree \(n\) is zero, since all terms will have been fully differentiated.
