2 to the power 16.
If you use them only once each, you can make 15 combinations. 1 with all four digits, 4 with 3 digits, 6 with 2 digits, and 4 with 1 digit. There is also a combination containing no digits making 16 = 24 combinations from 4 elements.
A quadrillion has 16 digits.
16 digits.
The question does not specify how the the digits are to be combined: addition, multiplication, subtraction, division, power, other.
2 to the power 16.
Oh, what a happy little question! To find the number of combinations with the digits 1, 2, 4, and 8, you can use a simple formula. Since there are 4 digits, you can arrange them in 4! (4 factorial) ways, which is 4 x 3 x 2 x 1 = 24 combinations. Just imagine all the beautiful possibilities you can create with those numbers!

Assuming that "number" means digits and that it is permutations (rather than combinations) that are required, the answer is 816 which is 281.475 trillion (approx).
If you include the combination which comprises no numbers (the empty set), then there are 16: 1 with no digits 4 with 1 digit 6 with 2 digits 4 with 3 digits, and 1 with 4 digits.

16 digits.
A quadrillion is a 1 followed by 15 zeroes (1,000,000,000,000,000).Therefore, there are 16 digits in a quadrillion.
