no, it is actually not a real number.

It falls under the category of a imaginary number which is the square root of -1 or as the variable i

Because the square root of -4 is 2i because the square root of 4 is 2 and if you take i out it will maek it a positive

so it goes like this

-4 SR= 2i

-9 square root= 3i

and so on

-1,0,or 1 the negative square root of four is negative two and the square root of four is two

The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i

The square root of 100 is 10 but positive and a negative is a negative so it is negative 10

Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.

The square root is generally positive or negative and it is only the context of the question that will tell you whether it is the positive root or the negative root. For example, if you are solving for the lengths of the sides of a square, a negative measure makes no sense so it must be the positive root.

√(a^2) That is |a| (the absolute value of a) Because if a is positive, a^2 is positive, and since √ is a positive square root, √(a^2) is a. If a is negative, a^2 is positive, and since √ is a positive square root, √(a^2) is -a. So if a is positive, √(a^2) is positive (which is a) If a is negative, √(a^2) is also positive (which is -a) So √(a^2) is |a| for every a.

Yes, as is the positive square root.

Every positive number has a negative square root.For example, 2.25 has the square roots -1.5 (and 1.5)

8 (positive or negative)

The principal square root is the non-negative square root.

the answer is undefined because a positive and a positive is positive and a negative and a negative is still positive

Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.

Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.

The answer is an imaginary number, because of the negative under the square root. The same number multiplied together will always be a positive number. For example, if you square negative one, the answer is positive one, because a negative times a negative is a positive. Because a square root undoes a square, there is no solution to the square root of a negative number. That's why your calculator could not compute this problem. However, there is a way to solve these types of problems by using imaginary numbers. The answer is 13i, where i is the square root of negative one.

using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number

Positive or negative (√8 * i) = Positive or negative 2.828i

Every positive number has two square roots: one negative and one positive. So negative sqrt(7) < negative sqrt(3) < positive sqrt(3) < positive sqrt(7)

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 answer is 2i. When dealing with negative square roots, the expression i is used to represent the square root of -1.

The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.

I think it is Xi (whatever the square root of the positive is times i). i is an imaginary number that when you square it, it becomes negative. eg. the square root of -4 is 2i. Without "i", it would be impossible to square root a negative number, as any number times itself will always equal a positive.

It depends on whether you take the positive square root of 4 (YES) or the negative square root of 4 (No).
