    Your answer is the same as the book's. The only difference is that, unusually, your book does not apparently care whether or not you "rationalize" the denominator.

    The book answer and your answer are the same. The difference is that you rationalised the denominator which is usually the preferred way.

    To get from your answer to the book answer divide by \frac{\sqrt6}{\sqrt6}
