MMMDCIX
3,609 in Roman numerals is MMMDCIX.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which happens in this case.

Step-by-step conversion of 3,609:

1. MMM = 1,000 + 1,000 + 1,000 = 3,000 → M repeated 3 times.

2. D = 500 → represents hundreds.

3. C = 100 → represents hundreds.

4. IX = 10 - 1 = 9 → subtraction rule used.

So, 3,000 + 500 + 100 + 9 = 3,609, or MMMDCIX in Roman numeral form.
