When you ask someone to write the largest 3-digit number and there respond will be 999.Lets be Logical, but we can go bigger then 999.


Some may get the "power" brainwave and think of 999 (99 to the power of 9), which calculates out as 99×99×99×99×99×99×99× 99×99.


Even better is 999 (9 to the power of 99) which calculates out as 9×9×9×9×9×9×9 ... and so on 99 times.


The correct answer, however, if you extend the idea even further ends up as... 99^9 (9 to the 9th power of 9).
