How many 3 -digit even numbers can be formed from the digits 1, 2, 3, 4, 5, 6 if the digits can be repeated?

Explanation

To solve the problem of how many 3-digit even numbers can be formed from the digits 1, 2, 3, 4, 5, and 6 with repetition allowed, we can follow these steps:

### Step 1: Identify the last digit
Since we are forming an even number, the last digit (the units place) must be an even digit. From the given digits (1, 2, 3, 4, 5, 6), the even digits are 2, 4, and 6. Therefore, there are 3 options for the last digit.

**Hint:** Identify the even digits from the given set to determine the options for the last digit.

### Step 2: Determine the first digit
