Question 242112: how many different license plates are possible using 2 letters followed by 3 digits if letters can be repeated?

If only the letters are repeatable then each letter spot has 26 chances, and each number spots would decrease...such that n x (n-1) x (n-2) etc.
so it would be 26 x 26 x 10 x 9 x 8
if both are repeatable then it would be 26 x 26 x 10 x 10 x 10
hope this helps
