Negative square root is -√

Square root of negative one is i.

It is a minus sign followed by the radical or a minus sign followed by the number to a power of 0.5 or 1/2.

There are no explicit symbols. The non-negative square toot is called the principal square root.

Because there is no "real" sqrt of a negative number, i is used as a symbol, eg sqrt -4 = 2i

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.

Yes, but it's not real. The symbol i is used to designate the square root of negative one.

The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.

The canonical example is the square root of -1. Mathematicians use the symbol i to represent it, electrical engineers use j because i is already busy.

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.

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.

The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.

The symbol "i" is an imaginary number used in algebra, equal to the square root of negative one.

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.

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.
