None. Nine digit number cannot be formed using only five digits 1,2,3,4,5 in the case none of the digits can repeat. -------- Egad! I misread the question, apologies to the questioner. And thanks to Miroslav.
If repetition of digits isn't allowed, then no13-digit sequencescan be formed from only 5 digits.
9876543210, without using any mathemeatical operations.
If you mean in Roman numerals then: 753 = DCCLIII
There are 3,265,920 numbers that can be formed using all the digits. The answer to the question will depend on which one of these.
Yes and they are normally written out in descending order.
the largest five digit number that can be formed using the digits 7 and 9 is 97,000
If the digits are all different then 18. Otherwise, 192.
Without using exponents or factorials, that's it.
The largest integer that can be formed by using the digits only once each and simply arranging them in some order is 8740. Otherwise, using exponents, much larger numbers are possible.
