Question
**Problem:**

**Given:**

Arrange the following functions in increasing order according to their growth:

1. \(\sqrt{2}\)
2. \(\log n\)
3. \(n^2\)
4. \(n!\)
5. \(\log (\log (n^5))\)
6. \(n^n\)
7. \(2^n\)

**Solution:**

To solve this problem, compare the growth rates of each function as \(n\) approaches infinity. Generally, functions grow in this order:

\(\log n < \sqrt{2} < \log (\log (n^5)) < n^2 < 2^n < n! < n^n\)

This arrangement helps in understanding the relative scalability of different algorithms and mathematical expressions.

**Explanation:**

- **\(\log n\)**: Logarithmic function grows very slowly.
- **\(\sqrt{2}\)**: A constant, hence does not grow with \(n\).
- **\(\log (\log (n^5))\)**: A double logarithm function grows very slowly, marginally faster than a constant.
- **\(n^2\)**: Polynomial function, grows faster than logarithmic functions.
- **\(2^n\)**: Exponential growth, very fast increase with \(n\).
- **\(n!\)**: Factorial growth, faster than exponential as \(n\) increases.
- **\(n^n\)**: This is the most rapid growth function of all listed here.

Understanding these concepts is essential for analyzing algorithm efficiency and other computational problems.
