Concept: We will review the fundamental definition of a roman number, which is the representation of numbers into combinations of letters such as I, V, X, L, C, D, and M that are employed in different orders to form any particular number. For instance, the roman numeral for five is V.
The roman number 39 should be written down as instructed in the question. Let's first define a roman number so we can answer the question. Roman numbers are described as the conversion of numbers into a string of letters such as I, V, X, L, C, D, and M that are employed in different combinations to represent any given number. For instance, the roman numeral for seven is VII.
We must now determine the roman numeral for 39. We shall therefore divide 39 into four equal pieces, giving us 39 = 10 + 10 + 10 + 9. Now that we are aware, 10 is represented by the roman numeral X, while 9 is represented by the roman numeral IX.
Therefore, 39 may be expressed as 39 = X + X + X + IX in the roman numeral system. 39 = XXXIX can be used to represent it.
As a result, we obtain the roman numeral for 39 as XXXIX.
Hence, choice (1) is the best one.
