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. The formula for permutations of n objects taken r at a time is given by nPr = n! / (n-r)!. In this case, we want to arrange all 6 books, so we will use 6P6.

Using the formula 6P6:

6P6 = 6! / (6-6)! 6P6 = 6! / 0! 6P6 = 6! / 1 6P6 = 6*5*4*3*2*1 / 1 6P6 = 720 / 1 6P6 = 720

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