Assign the digits from left to right, using the largest possible digit in each case. Don't forget to reserve an even digit for the last position.
The largest three-digit even number that can be formed using the digits 3, 4, and 5 is 543. To determine this, we need to consider the possible arrangements of the digits. Since we want to create an even number, the last digit must be 4. The largest possible number for the hundreds place is 5, and the remaining digit, 3, goes in the tens place. Therefore, the largest three-digit even number using the digits 3, 4, and 5 is 543.
