You wish to create a 6 digit number. The only digits available are 2,3,4,7, and 8, but you can use multiple copies of these digits if you wish. How many different 6 digit numbers can be formed if the only digits available for use are 2,3,4,7, and 8

15,625 different six-digit numbers can be formed from 2,3,4,7, and 8

Step-by-step explanation:

A six-digit number literally has 6 numbers.

If the number is to be made from 2,3,4,7, and 8 (five numbers) with no restrictions whatsoever and each number can even appear multiple times.

The first digit of the six digit number can be occupied by any of the 5 available numbers to make up the six digit numbers, and the same can be said for any. of the digits of the six-digit number.

Number of ways this can be done = 5*5*5*5*5*5 = 15,625 ways.
