How many different arrangements of 9 letters can be formed if the first letter must be W or K (repeats of letters are allowed)?

Assuming you mean 26 letters of the alphabet, and not case sensitive:
The first letter is 1 of 2
The 2nd is 1 of 26
The 3rd is 1 of 26

The 9th is 1 of 26
--> 2*26^8
=~ 4.1765E11
