There are 24 different ways you could arrange four books on a shelf.
This can be calculated using the formula for permutations which is n! / (n-k)! where n is the number of objects to choose from and k is the number of objects to choose.
In this case, n is 4 (the number of books) and k is also 4 (since we are arranging all four books).
So the calculation would be:
4! / (4-4)! = 4! / 0! = 24
This means there are 24 different ways to arrange the books on the shelf.
