How many 13 digit numbers are possible by using the digits 12345 which are divisible by 4 if repetition of digits is not allowed?
If repetition of digits isn't allowed, then no13-digit sequencescan be formed from only 5 digits.
How many 3 digit numbers can be formed from the digits 1234?
64 if repetition is allowed.24 if repetition is not allowed.
How many 9 digit numbers which are divisible by 4 can be formed by using the digits 1 to 5 if repetition of digits is not allowed?
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.

It is 415968.
How many different two digit numbers can be formed using the digits 2 3 5 6 8?
20 of them, if repetition is not allowed.
How many 4-digit numbers can be formed by the digits 1 2 3 4 5 with repetition is allowed and that are divisible by 4?
125 different 4 digits numbers. To be divisible by 4, the last two digits must be divisible by 4, which means they must be: 12, 24, 32, 44 or 52 - 5 possible choices. For each of these there are 5 choices for the first digit and 5 for the second, meaning: total = 5 x 5 x 5 = 125
