Well honey, if you're talking about 9-digit numbers with repeating digits allowed, you've got 10 options for each digit (0-9), so that's 10 choices for each of the 9 digits. So, the total number of combinations would be 10^9, which is a whopping 1 billion possible combinations. Hope that clears things up for ya!

Given that in a combination, 123124125 is the same as 111222345 or 321521421 etc (the order does not matter), I make the answer 8,697,700 - anyone willing to check?
This is much smaller than the 900,000,000 nine-digit numbers that do not have leading zeros, or the 999,999,999 nine-digit number including leading zeros.

What are all numeric 4 digit combinations?
There are a lot of them, so I'm sure you don't want us to list them all. If you want 0-9, and are happy with repeat digits, then it's 10*10*10*10 = 10000 combinations. If it's 1-9 and are happy with repeat digits, then it's 9*9*9*9 = 6561 combinations. 0-9 without repeat digits is 10*9*8*7 = 5040 combinations 1-9 without repeat digits is 9*8*7*6= 3024 combinations
How many 5 digit numbers from 1 0 6 2 9 and 7 have digits whose product is equal to 4?
If you are not allowed to repeat the digits then the answer is clearly 0.If you are allowed to repeat digits then the only way you can possibly reach a product of 4 is by using a combination of 3 "1's" and 2 "2's". The possible combinations are therefore:22111212112112121112122111212112112112211121211122Thus there are 10 numbers which meet the criteria.

How many 4 digit combinations can be made from 6 digits?
Oh, dude, you're hitting me with some math vibes here. So, if you have 6 digits to choose from to make a 4-digit combination, you can calculate that by using the formula for permutations: 6P4, which equals 360. So, like, you can make 360 different 4-digit combinations from those 6 digits. Math is wild, man.
What is this called when the digits in the number repeat?
repetition
