A four-digit number is to be made using the digits 1, 3, 5, and 8.

How many numbers can be made if repeated digits are allowed?

Answer 1

Since each digit can be repeated, there are 4 options for each digit.

Therefore, the total number of possible four-digit numbers that can be made using the digits 1, 3, 5, and 8 with repeated digits is:

4 x 4 x 4 x 4 = 256
