Is it true that square root symbol means +ve sq root only? [#permalink]

Hi, I hope this is the right place to ask this question.
As far as the GMAT is concerned, does the symbol for the square root of a number (don't know how to type it here) mean the positive square root only?
For example, even though there are 2 numbers whose square is 9, if I see square root 9 on the gmat, should I assume it means the positive number 3 only?
Thank you very much!
