Question

The question reads: If (2a)(2b)(2c)=64, then whatis 2a+2b+2c?
This is a multiple choice question on thetextbook.
I have figured out that a+b+c =6, but how can this help infinding out the value of theexpression without having to look at the possible answers? Is there a more direct approach?
Your help in explaining this will be much appreciated.
Thanks.

Explanation / Answer

I see what you mean that a+b+c=6 because if you plug in 3, 2,and 1 then it still works because 3+2+1=6: (23)(22)(21)=64 This is most likely the most direct approach that you couldhave. Philippians 4:13
