All five digit numbers have three digits. The smallest five digit whole number is 10,000
To form a 7-digit number using the digits 1, 2, 3, 4, and 8, we can use any of the five digits for each of the seven positions. Since repetition of digits is allowed, the total number of 7-digit numbers is calculated as (5^7). Thus, (5^7 = 78125). Therefore, there are 78,125 possible 7-digit numbers.

All five digit numbers have three digits. The smallest five digit whole number is 10,000
It is 120 if the digits cannot be repeated.
There are only five distinct odd digits.
To form a 5-digit number using the digits 1, 2, 6, 7, and 9 without repetition, we can use all five digits. The number of different arrangements of these 5 digits is calculated by finding the factorial of the number of digits, which is 5!. Therefore, the total number of 5-digit numbers that can be formed is 5! = 120.
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.
the largest five digit number that can be formed using the digits 7 and 9 is 97,000
