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.
it looks like a check mark. it is called the radical. it looks like this --> √
The square root symbol (âˆš) 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 '-'
Descartes invented the symbol used to indicate a square root, known as the radical symbol, which is shaped like a check mark. He also came up with modern exponential notation.
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 ( âˆš ) followed by a line above what's in the radical, designates positive square root.
No negative number can have a real square root.In math and engineering, the symbol ' i ' is used to representthe square root of -1 .Then the square root of -19 can be written as 4.3589 i (rounded).
The symbol you should be looking for is " √ ".
Leonhard Euler, an 18th Century mathematician, invented it. But the square root was used before him by the Greeks.
"/" is the root directory in Linux. Make sure not to confuse this with the "/root" directory, which is the home directory for the user "root" (similar to "Administrator" on Windows)
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)
The sign that is used for the square root is actually a root sign: the little 2 before it denotes that it is the square root. A little 3 would indicate it is a cube root, a little 4 that it is a fourth root and so on. However, conventionally, if no number is shown, it may be assumed that it is the square root.
┴ that one. Sometimes it'll have a small square to indicate a right angle.
According to Wikipedia, article on "Square root": "The symbol 'âˆš' for the square root was first used in print in 1525 in Christoph Rudolff's Coss, which was also the first to use the then-new signs '+' and 'âˆ’'."
The 'radical': √
Negative square root is -√Square root of negative one is i.
AryabhataThe symbol √ for the square root was first used in print in 1525 in Christoph Rudolff's Coss, which was also the first to use the "new" signs '+' and '-'.
There are no explicit symbols. The non-negative square toot is called the principal square root.
The symbol "i" is an imaginary number used in algebra, equal to the square root of negative one.
