**Tirne**, Wednesday, April 2, 2014 at 12:20am1) B .. Because since they're both sqrt7 base, you can just subtract them.

2) A .. You have to simplify sqrt12 to sqrt4 times sqrt3, so you will get 2(2)(sqrt3) + sqrt3 .. which will turn into 4sqrt3 + sqrt3. Since they're the same base again, it will be 5sqrt3.
