anonymous · Answer

200=100*2=10^2*2 and 8 = 2*2*2=2^2*2

anonymous · Answer

my answer choices are  A.-3 sqrt 2 B .-187 sqrt 2 C. 187 SQRT 2 D. -25 SQRT 2

anonymous · Answer

so you have 162 as 9^2*2, and 200 as 10^2*2m and 8 as 2^2*2 so...

anonymous · Answer

9 can come out, 10 can come out, 2 can come out. so you will have -27sqrt (2)+ 20sqrt(2)-18sqrt(2), and you can add the numbers in front if the number in sqrt is identical.
