Question

A security system requires a five-digit passcode where each digit can be any number from 1 to 9. How many possible passcodes can there be?

Answer 1

10,000 possible combinations.

Assuming repetitions are allowed, and there are no other restrictions, you have \(9\times9\times9\times9\times9=9^5\) combinations.
