The symbol used to indicate a nonnegative square root.
The symbol √ for the square root was first used in print in 1525 inChristoph Rudolff's Coss, which was also the first to use the then-new signs '+' and '-'
No, there is no such requirement or convention.
Leonhard Euler, an 18th Century mathematician, invented it. But the square root was used before him by the Greeks.
The 'radical': √
It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.
The symbol used to indicate a nonnegative square root.
Radical Sign
it looks like a check mark. it is called the radical. it looks like this --> √
The square root symbol (√) was first used in 1525, by Christoph Rudolff, and is called a radical.
That symbol is called the radical.

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.
No, there is no such requirement or convention.
Yes, but it's not real. The symbol i is used to designate the square root of negative one.
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
The symbol you should be looking for is " √ ".
