In todays modern usage of Roman numerals they are: MMIV MMV MMVI and MMXIV respectively.
But the ancient Romans would have wrote the equivalent of 2004 and 2014 quite differently than we do today.
2004 = MMIV 2005 = MMV 2006 = MMVI
2004=mmiv 2005=mmv 2006=mmvi
In Roman Numerals2004: MMIV 2005: MMV 2006: MMVI 2014: MMXIV
2004--mmix 2005--mmx 2006--mmxi
Super Bowl 2004 - XXXVIII = 38 Super Bowl 2005 - XXXIX = 39 Super Bowl 2006 - XL = 40
2004 = MMIV 2005 = MMV 2006 = MMVI
2004=mmiv 2005=mmv 2006=mmvi
2004 = MMIV 2005 = MMV 2006 = MMVI
In Roman Numerals2004: MMIV 2005: MMV 2006: MMVI 2014: MMXIV
2004--mmix 2005--mmx 2006--mmxi
Super Bowl 2004 - XXXVIII = 38 Super Bowl 2005 - XXXIX = 39 Super Bowl 2006 - XL = 40
