24 of them.
How many whole numbers can be made from 4 7 8?
INFINITE
How many numbers can be made from four digits when two are the same?
I assume you mean how many 4-digit numbers can be made from a set such as {A,A, B, C} where A, B and C are single digits. There are 12 such numbers.
How many combinations of four digits can be made from 1-44?
45
How many 4 number combinations can be made out of 3 numbers?
None. You do not have enough numbers to make even one combination.
How many 4 digit numbers are possible by 9 and 6?
There are 16 4-digit numbers that can be made up from 9 and 6.
How many 3 digit numbers can be made using the digits 3 4 5 and 6 if the digits can repeated?
There are 4 options for the hundreds digit (3, 4, 5, or 6), and 4 options for the tens digit (including the possibility of repeating the hundreds digit). Similarly, there are 4 options for the units digit. Therefore, the total number of 3-digit numbers that can be formed using the digits 3, 4, 5, and 6 with repetition allowed is 4 x 4 x 4 = 64.
If using numbers 1 through 4 how many different 4 digit combinations can be made?

Who made the number 4?
Egyptians made the numbers 4 back in B.C.
If using numbers 0 through 9 how many different 4 digit combinations can be made?
To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
If using numbers 1 through 8 how many different 4 digit combinations can be made?
15
