Answer:
Is it 2160?
Step-by-step explanation:
This is permutation
Imagine □□□□□, each □ represents a digit
For the 1st □, there are 6 choices, since "0" cannot be the first digit, or else it is not a 5-digit number
For the 2nd □, there are 6 choices (1 out of the 7 number is already used)
For the 3rd □, there are 5 choices (2 out of 7 numbers are used)
And so on.....
Therefore,
6×6×5×4×3 = 2160
