The identity of the person is not known. Some people believe that the symbol comes from the first letter of the Arabic word for root. Others believed that it comes from the letter "r" from the Latin word, radix = root.
It was first used in print by Christoff Rudolff in 1525 in Die Coss.
The origin of the root symbol √ is largely speculative. Some sources imply that the symbol was first used by Arab mathematicians. One of those mathematicians was Abū al-Hasan ibn Alī al-Qalasādī. Legend has it that it was taken from the Arabic letter "ج" (ǧīm), which is the first letter in the Arabic word "جذر" (jadhir, meaning "root"). However, many scholars, including Leonhard Euler, believe it originates from the letter "r", the first letter of the Latin word "radix" (meaning "root"), referring to the same mathematical operation. The symbol was first seen in print without the vinculum (the horizontal "bar" over the numbers inside the radical symbol) in the year 1525 in Die Coss by Christoff Rudolff, a German mathematician.

Mathematical symbol that was introduced in 1525?
The radical symbol for square root, without the vinculum above the radicand, was introduced in 1525. The first author to use it was Christoff Rudolff.
What would be of the square root of a number if there is no sign in front of the square root symbol?
If unspecified, the square root is the principal root, which is the positive root.
What is the symbol used to indicate the positive square root of a number?
It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.
Could a negative number be under a square root symbol?
Actually a negative number can be under a square root symbol. This becomes very useful in electrical calculations. The square root of -1 is j. That is, j2 = -1.
What do you call the number under the square root symbol?
The radicand.

What is the number outside the square root symbol?
It's a little hard to be sure what you mean by this question without seeing what you are looking at. I can think of two likely possibilities: 1. A number which is the same size as the square root symbol and written at the same level but located just in front of the symbol. This would just be a multiplier. 2. A smaller, superscripted number, possibly tucked into the angle at the front of the square root symbol. In this case, it isn't really a square root symbol anymore. It's a symbol for the root indicated by the superscriped number. For instance, if the superscripted number is a three and the number inside the root symbol is 8, this would represent the cube root of 8, or 2 (2x2x2=8).

What is the square root symbol put before a number to show that a root of it is to be found?
√16=4
What is the number i?
i is the symbol for an imaginary number, a complex number with the property i2=-1. The square root of a negative number is the square root times i. For example, the square root of -9 = 3i.
What mathematical symbol do you use when finding the square root of a number?
The mathematical symbol one can use when finding the square root of a number is y2=a. In other words y is a square number as a result of multiplying the number by itself (y x y)
What is the symbol used to represent the nonnegative square root of a number?
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
The square root of -17 is what kind of number?
An "imaginary" number. Those number are called imaginary for historical reasons, but they have very "real" practical applications. The result is written as root(17)i (replace root(17) with the square root symbol).
What does a radical symbol refer to?
A radical symbol indicates taking a root. A radical symbol alone indicates a square root (or equivalently, raising to the 1/2 power). If there is a small superscript number just to the left of the radical, then that indicates which root to take (square root for 2, cube root for 3, forth root for 4, fifth root for five, etc). This means raising to the 1/x power, where x is the small superscript number to the left of the radical.
