Exercises 54 and 55 use L'Hôpital's rule from calculus.

a. Let b be any real number greater than 1. Use L'Hôpital's rule and mathematical induction to prove that for all integers \(n \geq 1\),

\(\lim _{x \rightarrow \infty} \frac{x^{n}}{b^{x}}=0\) .

b. Use the result of part (a) and the definitions of limit and of O-notation to prove that \(x^{n}\) is \(O\left(b^{x}\right)\) for any integer \(n \geq 1\).
