6 choices for the first digit
6 choices for the second digit
6 choices for the third digit
6 choices for the fourth digit
6 x 6 x 6 x 6 = 6^4 = 1296 combinations

number of combinations for each digit is base
number of digits is the power to which the base is raised
number of combinations = 6 ^4 = 1296
