Answer 1

Answer:

5040

Step-by-step explanation:

There are 7 letters, and each letter is unique (there are no duplicates).

There are 7 letters that can go first.  After that, there are 6 letters remaining that can be second.  Then 5 letters in the third space, and so on.

So the number of ways it can be arranged is simply 7 factorial:

7×6×5×4×3×2×1 = 5040
