)another algebra problem

simplify

sqr(24^3y)
--------------
sqr(3xy)


I'm way off on this one. Can someone break it down?

oops sorry, I screwed up.

sqrt(24^3 * y) / sqrt(3xy) =
sqrt(13824y) / sqrt(3xy) =
sqrt(13824y / 3xy) =
sqrt(13824 / 3x) =
sqrt(4608 / x)

?

the more I look at the equation in the book, the more I think they put it together wrong. Thanks for eveyones response.
