I thought it only switched when mult. by a negative something. Secondly, I want to know what is the thinking guiding 1/x >1/y. I didn't think like this when I was trying to solve this problem.2) text: Alternatively, if Xsq.rt2 and y>sq.rt.2 then xy>2. But xy =2, so one of x or y must be less than sq.rt.2 and the other must be greater than sq.rt.2, since x sq.rt.2".I am really lost in the understanding of 2)sq. rt.2 means square root. of 2 1   L A T E S T    R E P L I E S    (Newest First) Joe Komagawa Posted - 12/01/2013 : 00:24:15 #157 answer is A y>sq.rt.2
