It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.
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.
Yes, but it's not real. The symbol i is used to designate the square root of negative one.
a+ square root of b has a conjugate a- square root of b and this is used rationalize the denominator when it contains a square root. If we want to multiply 5 x square root of 10 by something to get rid of the radical you can multiply it by square root of 10. But if we look at 5x( square root of 10 as ) 0+ 5x square root of 10 then the conjugate would be -5x square root of 10
The square root symbol (√) was first used in 1525, by Christoph Rudolff, and is called a radical.
