The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
The is only one unambiguous way and that is to use the modulus, thus: |√x| Some people do use +√x but, of course, this could be mean add the square root -whatever its sign.
There are no explicit symbols. The non-negative square toot is called the principal square root.
It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.
The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.
