Most people prefer to write numbers using digits since this is far shorter than writing out the relevant words.

I guess the expected answer is 97210. Using factorials and exponents very much greater number can be obtained. For example, 97210 is a number with 6880 digits. And that is without using factorials.
The number 1,234,567,890,123 has thirteen digits.
This is a question of permutations; the answer is equal to the factorial of 5 (number of digits) divided by the factorial of 3 (number used in each selection), written 5! / 3!. This equals 120 / 6, or 20 ways.
The smallest number that someone can get using the 91764 digits is 14679. The secret is to arrange the digits from the least number to their greatest number.
Expressed in digits, this is equal to 1,002,003.

3.14 (That number is rounded. 'Pi' can't be completely written out with digits.)
The number 100, using digits 0 thru 8, would equal the number 81 using digits 0 thru 9. 1x92 + 0x91 + 0x90 which is 1x9x9 + 0x9 + 0x1

none because you are counting
write the largest number you can make using each of the digits 7,1,0,2, and 9 just once
99 is the largest two digit number. If I can use the digits anyway I want, then 9 to the 9th power is larger
binary.
The only digits in binary (base 2) are 0 and 1. All numbers are represented with those 2 digits. For example: 12 is written as 1100. 33 is written as 100001.
TWO digits are in the number 30, 3 and 0
