Question 102399: Good Evening Tutor,
I need to check my answers for these two problems could you tell me if I have them correct?
1. Simplify 2 sqrt of 12 + 4 sqrt of 27
I have 2 sqrt of 39 (correct?)
2.) Simplify 6 sqrt of 2 - 6 sqrt of 7
is this 6 sqrt of 5?
Thank you for your help.

You can put this solution on YOUR website!
1. Simplify 2 sqrt of 12 + 4 sqrt of 27
= 2*2sqrt(3) + 4 sqrt(2)
= 4[sqrt(3) + sqrt(2)]
-----------------------------
2.) Simplify 6 sqrt of 2 - 6 sqrt of 7
= 6[sqrt2-sqrt7]
-------------------------
This is a far as you can go with these two problems.
