The smallest four digit number with four different digits is 1023.
Solution:
Four smallest digits are 0, 1,2 and 3. In order to write the smalest 4-digit number using digits 0, 1, 2 and 3, we put the smallest digit 1 (Except 0) at the place having the highest place value. The largest digit 3 is put at the right most place i.e. at unit's place, the digit 2 is put at the ten's place and the digit 0 is put at the hundred's place. Hence, the required largest number is 1023.
The smallest four digit number with four different digits is 1023.

The total number of 5 digit numbers = 90000.
Solution:
There are 10 digits i.e., 0, 1, 2, 3, 4, 5, 6 ,7, 8, 9.
We can not use '0' at the place having the highest place value.
So, we can use only 9 digits at the place having the highest place value.
Also, we can use 10 digits at the remaining places.
So, total numbers of four-digit numbers = 9 × 10 × 10 × 10 × 10 = 90000
The total number of 5 digit numbers = 90000
