Help me finish solving or tell me if I messed up?
√2 (6b√16 - 2b)
6b√32 - 2b√2
6b√4*8 - 2b√2
6b*2√8 - 2b√2
12b√8 - 2b√2
Next would I make the √8 A √4*2 ?

Question

Help me finish solving or tell me if I messed up?
√2 (6b√16 - 2b)
6b√32 - 2b√2
6b√4*8 - 2b√2
6b*2√8 - 2b√2
12b√8 - 2b√2
Next would I make the √8 A √4*2 ?

anonymous · Answer

you can futher break this 12b√8 - 2b√2 into 

12b√4*2 - 2b√2

then you can finish up from there

anonymous · Answer

then, 12b*2√2 - 2b√2
         24b√2 - 2b√2
         24*-2 = -48 so
  -48√2

anonymous · Answer

But that isn't one of the options so maybe I could simplify -48 somehow?

anonymous · Answer

No you did it wrong

anonymous · Answer

Which part?

anonymous · Answer

this

12b*2√2 - 2b√2

will then become

24b√2 - 2b√2
22b√2

anonymous · Answer

the question is even easier if you hadnt done the distribution in the beginning.

√2 (6b√16 - 2b)
√2 (6b*4 - 2b)
√2 (24b - 2b)
√2 (22b)

True, thank you! I confused the multiplication with addition I see it now.
