Compute: `(20 !)/(18 !)`

Explanation

To solve the expression \(\frac{20!}{18!}\), we can follow these steps:

### Step 1: Understand Factorials
Factorials are defined as the product of all positive integers up to a certain number. For example:
- \(n! = n \times (n-1) \times (n-2) \times \ldots \times 2 \times 1\)

### Step 2: Write \(20!\) in Terms of \(18!\)
We can express \(20!\) in terms of \(18!\):
