Solution:
In the Roman numeral system, there isn't a single symbol to represent the number 10,000. Instead, it is represented as a combination of existing Roman numerals.
So, the number 10,000 is written as "X̅" (an 'X' with a line over it). The line above a Roman numeral indicates that the number is multiplied by 1,000.
Remember, the basic Roman numerals are:
I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1,000
When a line is placed over a number, it multiplies the value by 1,000, so X̅ = 10,000, C̅ = 100,000, etc.
