The radical symbol √

The general case is just called "Root" and it continues to increase to "Square Root" then to "Cube Root" and so on.

The square root symbol (âˆš) was first used in 1525, by Christoph Rudolff, and is called a radical.

The symbol for a a square root sign is: √

The only thing that a square root symbol does is that it symbolises an operation (taking the square root) of whatever is under the sign.

The square root symbol is the radical sign, √.

It is imaginary; we denote sqrt of -1 = i square root (-4) = ± 2i

The square root symbol is like a tick with a line connected to the top. Go to http://en.wikipedia.org/wiki/Square_root and the square root symbol is displayed.

If unspecified, the square root is the principal root, which is the positive root.

The symbol is not considered an integer. Thevalue of the square root is, though.

The radical symbol √ (with a line over what you're taking a root of) denotes root.The symbol without any other numbers, means square root, while with a number like 3√ means take cube root, 4√ fourth root, etc.If you want to type this symbol in Windows, hold down the key on the keyboard, then type (on the number pad) 251, then let go of the key.You can also denote roots by fractional exponents: 1/2 power is the square root,1/3 power is the cube root, etc and this works if you have an xy (exponentiation)key on your calculator and want to compute roots.The symbol used to make a root is √

There are many ways one can make the square root symbol on their computer. One can make the square root symbol on their computer by holding down the ALT key as you type 251.

To type the square root symbol on ypur keyboard press and hold alt and type 251.

It is still called a square root.

A square root!

The square root of the square root of the square root of something is called the 8th root. The 8th root of pi is approximately 1.15383506784999.

The number of which the square root is to be found is called the "radicand." The symbol before the number is called the radical sign. ( √ ) E.g. √4 = 2, √25 = 5

Square roots of negative numbers are what are called imaginary numbers. The building block of imaginary numbers is the symbol i which is defined as the square root of negative 1. The square root of other negative numbers can be expressed using i. For example, the square root of negative sixteen is 4i, the square root of negative nine is 3i and so on.

I cant use the square root symbol so lets use the word "root" to represent square root. The answer would be 4root2

A radical.

It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.

Restricting the discussion to real numbers for now. In this case, the square root is only defined for non-negative numbers; the principal square root of a positive number is the POSITIVE square root. For example, both +5 and -5 are square roots of 25, since both - when squared - give you 25. But the positive square root (+5) is called the principal square root, and if you write the square root symbol, that's the number usually meant.

There is no single square root button on a keyboard. You can sometimes get the square root symbol by holding down alt and pressing 2 then 5 then 1 (or alt + 251). If that doesn't work, you could copy and paste it. √ (that square root sign is from pressing alt + 251)
