The √ symbol, universally recognized as the "Square Root", is one of the fundamental symbols in mathematics, representing the operation to find a number that, when multiplied by itself, yields the given number.
A symbol for square roots, written as an elaborate R, was invented by Regiomontanus (1436–1476). An R was also used for radix to indicate square roots in Gerolamo Cardano's Ars Magna.
The root symbol (√ ) is used to represent the square root of any number. For example, the square root of 2 is represented by √2. Similarly, for other natural numbers, such as 5, 6, 7, 8, 10, etc. we can denote the square roots for them as √5, √6, √7, √8, and √10, respectively.
The square root symbol refers to the principal square root, which is the positive one. The two square roots of a negative number are both imaginary numbers, and the square root symbol refers to the principal square root, the one with a positive imaginary part.
The square root symbol "\(\sqrt{\ }\)" is also sometimes called a radical. The number or expression underneath the top line of the square root symbol is called the radicand. For example, in the expression \(\sqrt{2x+3}\), the radicand is \(2x+3\).
This is the special symbol that means "square root", it is like a tick, and actually started hundreds of years ago as a dot with a flick upwards. It is called the radical, and always makes mathematics look important! We can use it like this: and we say "square root of 9 equals 3"
