Hey guys, sorry but I have a small stupid question.
look at the following question:
if xyz≠0, then what is the value of x^4:y^2?
my question is ONLY: WHAT DOES XYZ≠0 MEAN? what are they trying to tell me with that?
in an other example they ask this.
if x≠-(1:2), then 6x^2+11x-7:2x-1=
my question here again is also: WHAT DOES x≠=-(1:2) mean? what are they trying to tell me with that? that x can be everything except -1:2?
thanks in advance everybody..im making the gmat 16 november, please pray that I pass it.
