What is 500000000 in roman numerals?

Answer 1

The ancient Romans had no real reasons for such large numbers as 500,000,000 but the Roman numeral system is and was capable of expressing the equivalent of half a billion into Roman numerals by means of brackets and superscripted numerals in a similar way that today we would now use exponents to increase the values of numbers and so five hundred million can be expressed in Roman numerals in any of the following formats:-

(M)^D which means 1,000*1,000*500 = 500,000,000

(D)^M which means 1,000*500*1,000 = 500,000,000

In modern terms we can now express 500,000,000 as 5.0*10^8 in scientific notation
