Answer 1

Your answer is correct.

√54 = √9√6

√54 = 3 √6

Answer 2

3 radical 6 is the answer: are you sure that the problem wasn't asking for the cube root--in that case the answer in the book would be correct. If this is not the case, the book happens to be wrong in this case: it happens.

Answer 3

sqr(27x2)

sqr(2x3x3x3)

3 sqr(6)

you got it.
