If A = {1, 2, 3} and B = {4, 5}, find `AxxB`, `BxxA` and show that `AxxBneBxxA`.

Explanation

To solve the problem, we need to find the Cartesian products \( A \times B \) and \( B \times A \) for the given sets \( A \) and \( B \), and then show that \( A \times B \neq B \times A \).

### Step 1: Define the Sets
Let:
- \( A = \{1, 2, 3\} \)
- \( B = \{4, 5\} \)

### Step 2: Calculate \( A \times B \)
