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.
Usually, in code, the square root symbol is denoted as: sqrt() where the number inside the square root is written inside the brackets. For example, if you wanted the square root of 64, write: sqrt(64)
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 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 '-'
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 " √ ".
