ok im having a bit of a problem rationalizing denominators.

i have 2 to the root of 3 +4 divided by the root of 3.

I have tried multiplying the top and bottom by the root of 3 and the answer, but then i get stuck at this part. Do i multiply 4 by 4 and make it a root? or am i doing something wrong here?

the answer at the back of the book is 6 root 3+ root 6 over 3


Plz help, this is due 2morrow

Do this. I used my calculator and evaluated 2 to the sq root 3 + 4 divided by the sq root 3 and found 5.6314 for an answer. Then I took the answer you gave that appears in the back of the book and I found 11.2088. Check your answer with the calculator and see what you get. Verify my numbers.The answer in the back of the book may be wrong.
