This was a secret to me up until now. So, just to rephrase what you explained: if we (test-takers) perform a square root operation during any of our calculations, then we have to assume both +ve and -ve values; if GMAT uses a *square root sign* in one of its problems, then we have to consider ONLY t...

Why is that? I am missing the point here.Rahul@gurome wrote:The answer is equal to the greatest common divisor of 1/5 and 1/7 = 1/35.

Sq. root (Real Number)
http://s4.postimage.org/rPAKr.jpg Please refer to the problem attached as an image. Question: Should we assume that only positive values will result from a square root? For instance, if we assume x = 1, then Sq root (x) = sq. root (1) = +1 or -1. In this case, the correct answer to the above proble...

@pesfunk: The OA is already mentioned. Read the question carefully; it doesn't ask for the area of the largest triangle that can be inscribed in the circle. If you have a different answer, then please share your explanation (how you arrived at the answer). It will be helpful to others also.
