Jim@StratusPrep and Matt@VeritasPrep: Ok but what rule is being applied here? PEDMAS? Because we have to solve the Parenthesis first? And the square root falls in the category of Exponents? 1) But if this is true then for the first statement where "√x^2 = 4". The square root falls in the...

Brent@GMATPrepNow: Ok i get it. The target question has already told us that x < -5 so we dont need to TEST it whether it is true or not. That was the mistake i was making. Right.
Matt@VeritasPrep: Do we always consider these kind of results in an "OR" manner?

1) By conflicting i mean that first value is x < -5 and second value is x > - 1. How can it be possible that X is greater than -1 but less than -5. So my questions is that IF X COULD be x > -1 however the value COULD be less than -5 in that case the statement is SUFFICIENT. So: - You can say that X ...
