rationalizing the denominator

Simplify by rationalizing the denominator

When I worked the problem

7/sqrt[5] sqrt[6]

I got

7(sqrt[5] +sqrt[6])

Can anyone tell me if I worked the problem right?

I don't believe you even typed the questionm right. Could it have been
7/(sqrt(5)-sqrt(6)) =
7 * (sqrt(5)+sqrt(6)/(sqrt(5)-sqrt(6))((sqrt(5)+sqrt(6))=
7*(sqrt(5)sqrt(6))/(5-6) =
-7(sqrt(5)+sqrt(6))

Gene I had worked the problem already I just want to post the problem along with my answer in hope that someone could tell me if my answer to the problem is correct.

Did you read what I said? I guessed what the problem might have been by looking at your answer. If I guessed wrong then I still don't know if your answer is right. It is wrong by a minus sign if my guess was right. It is very wrong if the problem is as you typed it.
