Answer 1

625

Explanation:

"625

As we have first five letters namely {a,b,c,d,e} , first letter could be filled in five possible ways. Now, as letters can be repeated second place too can be filled in five possible ways and so too for third and fourth place. Hence we can have 5×5×5×5=625 possible four letter words." (socratic.org)
