Step-by-step explanation:

1. You have the following phrase given in the problem: 16 times as many books. You can conclude this is a multiplication word problem, because:

- Let's call the number of books.

- "As many boooks" indicates multiplication.

- 16 times means that should be multiplied by 16.

2. Then, you can conclude that the expression that best represent the phrase is:

Step-by-step explanation:

51^7 - 51^6  =                            => as 51^7 = 51^6 * 51

51^6*51 - 51^6 =                      => factor 51^6 form each terms

51^6(51 - 1)      =                       => as 51 -1 - 50

51^6* 50          =                      => as 50 - 2 * 25

51^6 ( 25*2)

so the original expression is divisible by 25
