2sqrt(3) ---------- -2sqrt(6) ?
OpenStudy (anonymous):
Same as above... the two's divide to get just -1... you get -sqrt(3)/sqrt(6)
OpenStudy (anonymous):
also the sqrt(6) can be rewritten as sqrt(3)*sqrt(2) so the sqrt(3) cancels with the 1 on top leaving: -1/sqrt(2) now u just have to rationalize the denominator
