### Induction Problems

#### 1. Use mathematical induction or strong mathematical induction to prove the given statements:
### (a)
\[
(2^n \cdot n!)^2 < (2n)! \cdot (n + 1), \text{ for all integers } n \ge 2.
\]

### (b)
Let \(\{F_n\}_{n=0}^{\infty}\) be the Fibonacci sequence. Show that \(\forall n \in \mathbb{Z}^+, F_n < \left(\frac{13}{8}\right)^n\). (Note, \(F_0 = \left(\frac{13}{8}\right)^0\))

### Explanation:

**Part (a):**
- The problem statement requires proving the inequality \((2^n \cdot n!)^2 < (2n)! \cdot (n + 1)\) using mathematical induction or strong mathematical induction for \(n \ge 2\).

**Part (b):**
- In this part, the goal is to show that for all positive integers \(n\), the \(n^{th}\) Fibonacci number \(F_n\) is less than \(\left(\frac{13}{8}\right)^n\).
- The Fibonacci sequence is defined by:
  \[
  F_0 = 0, \quad F_1 = 1, \quad \text{and} \quad F_n = F_{n-1} + F_{n-2} \text{ for } n \ge 2.
  \]

Both parts involve demonstrating the given inequalities using the principles of mathematical induction, a powerful method for proving assertions about positive integers.
