Step-by-step explanation:

The numbers from 1 to 9999 can be shown in the form of:

3xyz, x3yz, xy3z. xyz3

Each of x, y, z represent the digits from 0 to 9, so 10 ways each.

For each of the forms we have:

10*10*10 = 1000 ways and

Total of:

1000*4 = 4000 ways

By the way this is applicable to any digit.
