720. The first place can be any of the 6 items, the second can be any of the remaining 5 etc etc. 6 x 5 x 4 x 3 x 2 x 1 = 720.
The number of ways that 15 books can be arranged on a shelf is the same as the number of permutations of 15 things taken 15 at a time. This is 15 factorial, or 15!, and is 1,307,674,368,000.
4*3*2*1 = 24 ways.
2. If the books are x and y, then xy or yx are the only possible ways. Unless you allow for one book to the side of the other, one bok on top of the other, one book leaning partially on the other, etc. In that case, there are an infinite number of ways.
