Step-by-step explanation:
For the 4 digit case, the first digit must be either 5, 6, or 7, giving 3 possibilities.
The last three digits can be anything, so there are possibilities there. In total, that gives 72 possible 4-digit numbers.
Therefore, there are 192 total numbers greater than 5000 that can be formed with those digits.
