Assuming you mean permutations of three digits, then the set of numbers that can be made with these digits is:
345
354
435
453
534
543
There are six possible permutations of three numbers.
If the digits are all different then 18. Otherwise, 192.
There are 60480 numbers.
1 set
There are 4^6 = 4096 such numbers.
6*5*4*3*2*1=720
5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.
If the digits are all different then 18. Otherwise, 192.
10,000

100000 - including numbers with leading 0s
99999
Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
192, including ones containing repeat digits.

To form a five-digit number using the digits 1, 2, 3, 4, and 5, each digit must be used exactly once. Since there are 5 unique digits, the total number of different five-digit numbers that can be formed is given by the factorial of the number of digits, which is 5! = 120. Therefore, 120 different five-digit numbers can be formed using the digits 12345.
6 if you don't repeat any.
