How many different four-letter initials are there that begin with A?
26^3. There are 26 possible letters, so that is why we multipy by 26. Because there are 4 positions, and the first is taken with "A", that only leaves 3 positions left. As there are 26 possible letters in each position, you multiply by 26 three times, or, 26 to the third power.
