Question

anonymous · Answer

You got it.  I just checked your work. :)

anonymous · Answer

No, the last choice !!!

anonymous · Answer

√ 10 = √5 * √2
From there, factor only √2 out, in order to combine with other group!

anonymous · Answer

= √2 ( 4√5 - 5 )  +  √2 ( 2√5 + 4)
Can you combine them now?

anonymous · Answer

Note: √8 = 2√2

Chlorophyll.  Are you suggesting that she multiply √2 to both sides of the equation?  I didn't it worked like that.

anonymous · Answer

It works because I see the answer :)
