Question

You have seven different books. How many different ways may they be arranged on a bookshelf?

a) 42
b) 49
c) 56
d) 63

Answer 1

There are 5040 different ways the books can be arranged on the bookshelf.

Step-by-step explanation:

To find the number of different ways the books can be arranged on the bookshelf, we can use the concept of permutations. In this case, we have 7 books, so the number of arrangements is given by 7 factorial (7!).

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040

Therefore, there are 5040 different ways the books can be arranged on the bookshelf.
