lxl>0 is the answer all real numbers...

OpenStudy (mathteacher1729):

Not ... ALL of them... There is only one real number for which that is false. :)

OpenStudy (anonymous):

0?

OpenStudy (mathteacher1729):

Yup. :) |0| = 0 And obviously 0 > 0 makes no sense. So |x| > 0 for ALL real numbers is false, because of zero.
