Question

the number of possible 4-digit number combinations that can be made using 2 and 7 equal number times​????

Answer 1

Answer:

4 digit, 2 number … if I get you correctly then you mean something like aaaa aaaa

Now each of these X’s can be any value from 0→9 that mean 10 possibelities for each digit, consider it in the sense that, the first can have any value from 10 possibelities, for each of these possibilities the second can have any of 10 possibelities, and for each of those the third can have any of 10 possibelities and so on …

So your answer will be 10×10×10×⋯×10 and of course you have 8 of those tens so you get 108
