Step-by-step explanation:
For, calculate how many different three digit numbers can be written, we can use the rule of multiplication as:
5 * 4 * 3 = 60
1st digit 2nd digit 3rd digit
Taking into account that there is no repeating digits, we have 5 options for the first digits, this options are the number 5, 6, 7, 8 or 9. Then, we have 4 options for the second digit and then we have 3 options for the third digit.
