Yuo can make only one combination of 30 digits using 30 digits.
8*7*6*5*4 = 6720 of them.
You can make 24 numbers by rearranging the digits. However, you can make vastly more if you allow mathematical operations on the digits. For example, 3+5*8-6 = 37.
9,000 - all the numbers between 1,000 and 9,999 inclusive. * * * * * NO. Those are PERMUTATIONS, not COMBINATIONS. Also, the question specified 4 digit combinations using 4 digits. The above answer uses 10 digits. If you start with 4 digits, you can make only 1 combination.
Oh, what a delightful question! You can create the biggest number by arranging the digits in descending order. So, by using all the numbers 1 to 9, the largest number you can make is 987654321. Just like painting, it's all about arranging things in a way that brings you joy and beauty.
There are 192.
89,999 different numbers i guess

There are 4 options for the hundreds digit (3, 4, 5, or 6), and 4 options for the tens digit (including the possibility of repeating the hundreds digit). Similarly, there are 4 options for the units digit. Therefore, the total number of 3-digit numbers that can be formed using the digits 3, 4, 5, and 6 with repetition allowed is 4 x 4 x 4 = 64.

2 * 2 * 2 * 2 It's not possible to make 16 without using the same numbers twice or without using whole numbers.
456, 546 and 564 are three of the four possible even numbers.
With 123 digits you can make 123 one-digit numbers.
Using the combination C(4,3) I got the answer 24. Its either a combination or a permutation.
600 of them.600 of them.600 of them.600 of them.

3*3*2*1 = 18 of them.
