a. 6
b. 12
c. 24
d. 720

Answer 1

The number of unique ways to arrange six books on a shelf is 720.

Step-by-step explanation:

To find the number of unique ways to arrange the six books on a shelf, we can use the concept of permutations. The formula for permutations is n!, where n represents the number of items. In this case, there are six books, so the number of permutations is 6!.

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

Therefore, the correct answer is d. 720.
