The radical symbol ( √ ) followed by a line above what's in the radical, designates
positive square root.
There are no explicit symbols. The non-negative square toot is called the principal square root.
it looks like a check mark. it is called the radical. it looks like this --> √
Negative square root is -√Square root of negative one is i.
Because there is no "real" sqrt of a negative number, i is used as a symbol, eg sqrt -4 = 2i
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.

The 'radical': √
The symbol used to represent a nucleus is "Au", which is a combination of the atomic symbol and mass number.

Negative square root is -√Square root of negative one is i.
The symbol you should be looking for is " √ ".
Because there is no "real" sqrt of a negative number, i is used as a symbol, eg sqrt -4 = 2i

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).
