What is the symbol used to represent thenonnegative square root of a number?

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.

How can there be a square root of a negative number?

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.

What is the square root of negative forty eight?

Engineers and scientists do work with square roots of negative numbers, but when they do, the square root is called an "imaginary" number, and they need a special symbol for it. For our purposes, and the level of math typically encountered here on WikiAnswers, the best answer is simply to point out that you can't find any number which, when you multiply it by itself, gives you a negative answer, so there's no such thing as the square root of a negative number.

Why can't you square root?

Technically, you can. The set of imaginary numbers contains i, the symbol for the square root of negative one. But in the real world, a square is something multiplied by itself. You can't find two of the same things that will multiply to create a negative number.

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).


Can a perfect square have a negative square root?

If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
