Oh, what a happy little question! You have 9 choices for the first digit since you can't use 0, then 8 choices for the second digit, 7 choices for the third digit, and 6 choices for the fourth digit. So, you can form 9 x 8 x 7 x 6 = 3024 different 4-digit numbers from the given digits. Just imagine all the beautiful combinations you can create!

If the digits can be repeated, the answer is 94 = 6561.

If no repeats, the answer is 9*8*7*6 = 3024
