There are 2000 such numbers.
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.
Six hundred.
Six.
ten factorial = 10! = 3,628,800

To form a 5-digit number using the digits from 1 to 9 (without the digit 0) and allowing repetitions, each position in the number can be filled by any of the 9 digits. Therefore, for each of the 5 positions, there are 9 possible choices. Thus, the total number of 5-digit numbers that can be formed is (9^5 = 59,049).
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
