Question

HELP ASAP PLEASE

Answer 1

Wouldn't it be B? Once you multiply -10*-8 you would get get sqrt"+80". And then, you would get 4sqrt"5" like you did. That's why I think.

Answer 2

I think it's b

Answer 3

I think A is right

Answer 4

Im not sure though, hold on

Answer 5

But you would simplify 80, not -80. -10*-8=80. If one had to simplify -80 then it would be A. But in this case, it's B.

Answer 6

It is B
