If you use each number once, there are six combinations.
There are 3*2*1 = 6 of them.
18
The answer will depend on how many digits you have at your disposal. Working with the 10 digits, and barring leading zeros, there are 8,877,690 numbers.
-99
how many different ways can you use the digits 3 and to write expressions in exponential form/ what are the expressions
You would need infinitely many digits to write all numbers. However, to write all whole number (integers) you would need 4243.
There are 3*2*1 = 6 of them.
89,999 different numbers i guess

Different schemes have different id numbers of different lengths.
5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.
There are 41 of them.
how many different ways can you use the digits 3 and to write expressions in exponential form/ what are the expressions
If the digits are all different then 18. Otherwise, 192.
