Answer 3

Calculating the Number of Ways to Arrange 6 Different Books on a Shelf

To calculate the number of ways to arrange 6 different books on a shelf, we can use the concept of permutations. A permutation is an arrangement of objects in a specific order.

In this case, we have 6 different books to arrange on the shelf. The first book can be placed in any of the 6 available positions. Once the first book is placed, the second book can be placed in any of the remaining 5 positions. Similarly, the third book can be placed in any of the remaining 4 positions, and so on.

To calculate the total number of arrangements, we multiply the number of choices for each book together. Therefore, the number of ways to arrange 6 different books on a shelf is:

6 x 5 x 4 x 3 x 2 x 1 = 720

So, there are 720 different ways to arrange the 6 books on the shelf.
