Answer:

16.) 28 - 4√2 + 7√7 - √4 (1st choice)

17.) 17√3 (3rd choice)

Explanation:

16.) (4 + √7) (7 - √2)

4 × 7 = 28

4 × -√2 = -4√2

√7 × 7 = 7√7

√7 × -√2 = -√14

So, the answer is 28 - 42 + 77 - 4 (1st choice)

17.) 10√3 + 7√3

= 17√3

So, the answer is 173 (3rd choice)

Hope it helps and is useful :)
