The root There is some confusion on the questioner's part. A root is a root.

Numbers have many roots:

The square root of 64 is 8 since 8 squared is 64: 8² = 8 × 8 = 64

The cube root of 64 is 4 since 4 cubed is 64: 4³ = 4 × 4 × 4 = 64

The square root of a number x is sometimes called "radical x" because x appear after the radical (or square root) symbol: √x

As square roots are used a lot, it is also often abbreviated from "square root" to just "root", for example √2 can be read as "root 2" though to be strictly correct it is "square root of 2".

Roots also refer to solutions to equations (linear, quadratics, cubics, or higher polynomials) where they equal 0, for example x = -3 and x = 2 are the roots of the equation x² + x - 6 = 0; x = -2, x = 1 and x = 4 are the roots of x³ - 3x² - 6x + 8 = 0.

The square root of a negative value is called an imaginary number.

A root.

The ROOT

The number of which the square root is to be found is called the "radicand." The symbol before the number is called the radical sign. ( √ ) E.g. √4 = 2, √25 = 5

It is an imaginary number

The root of a number is any number that when multiplied by a certain number of times, it becomes the original number. The number of times the root has to be multiplied is called the index of the radical. The number that it becomes after it is multiplied is called the radicand. If the index is equal to x, and the radicand is equal to y, then the root can be expressed by " y to the (1/x)th power", or "y1/x".

its called a "perfect square"

Such a number is called, "The square root of 1".

The number is called a 'square root'.

The square root

Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".

That is called the square root of a number.

such a thing as this does exist but it is called an imaginary number

A perfect square.

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)

The square root

The square of that integer.

The square root of any negative number is not even a 'real' number. It's called 'imaginary', because there's no number you can multiply by itself to get a negative number. The square root of 101 is irrational.

no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.

If a number is squared you get a new number called the square of the given number. When the square root of the new number is taken you get back the original given number!

in math, a real number that is not the root of any polynomial with rational coefficients is called transcendental.

The square root of i=(i)^.5 = .707+.707i
