If the set A has 3 elements and the set `B = {3, 4, 5}`, then find the number of elements in `(A xxB)`.

Explanation

To find the number of elements in the Cartesian product \( A \times B \), we can follow these steps:

### Step 1: Identify the number of elements in each set
- Set \( A \) has 3 elements.
- Set \( B \) has 3 elements (since \( B = \{3, 4, 5\} \)).

### Step 2: Use the formula for the Cartesian product
The number of elements in the Cartesian product of two sets \( A \) and \( B \) is given by the formula:
