Thank you for the opportunity to help you with your question!

Since order does matter (this is because the word "cab" is different than "abc"), we can use the permutation formula: Start with the given formula Plug in (this is number of letters given) and (this is the number of letters we can use together at a time) Subtract to get 5 Expand 8!
