The negative square root of a number is expressed as -√n or -n^½.
The question probably may refer to the square root of a negative number.
In mathematics there is an identity i² = -1 so that i = √-1
The square root of a negative number can be shown in several ways.
For Example : √-36 = √( -1 x 36) = √-1 x √36
The square root of 36 is ±6, and the square root of -1 is i.
The solution to √-36 is therefore ±6i.

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).
