(1) if x^4<1 we can conclude that x is a positive or a negative fraction and thus smaller than 1. Sfufficient.
(2) if |x|/x = 1 we can conclude that x is positive, but we don't know whether it's a positive fraction or a positive integer (and what is the size of the integer). Insufficient

stat1 : X^4 will always be positive... hence for any x^4 to be less than 1 it has to be a number between 0 and 1 or 0 and -1..
