CDXXXIV
434 in Roman numerals is CDXXXIV.

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 434:

1. CD = 500 - 100 = 400 → subtraction rule used.

2. XXX = 10 + 10 + 10 = 30 → X repeated 3 times.

3. IV = 5 - 1 = 4 → subtraction rule used.

So, 400 + 30 + 4 = 434, or CDXXXIV in Roman numeral form.
