You would get (i square root 2) because you can not square root a negative number, the answer is imaginary.

Tmdkiller: Square root is NOT applicable to any Negative numbers eg -1 ,-2,-3 etc

You would get an "Error 2" on a scientific Calculator anyway. =)

squre root of -2 is 2i (where "i" is "iota" represents imaginary or complex number......

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Are negative square roots rational or irrational?

If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.


What is -18 times the square root of -16?

-2


What is the nonnegative square root of a number?

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.


How do you compute x if x equals negative under root 2?

Can to negative square roots ever be multiplied?

You must be careful when multiplying square roots of negative numbers; the same rules that apply for normal square roots do NOT apply. I will use shorthand root(x) for the square root of x. For example, root(2) x root(3) = root(2 x 3) = root(6), but you can't do this with square roots of negative numbers. For example: root(-2) x root(-3) = i root(2) x i root(3) = i2 root(6) = (-1) root(6) = -root(6). "i" is the imaginary unit.


What is the square root of negative 18 in radical form?

The square root of negative 18 is an imaginary number.The square root of positive 18 is [ 3 sqrt(2) ].If the 18 is negative, then scientists and engineers indicate its square root as 3i sqrt(2) . The little ' i ' indicates the square root of negative one.


What is the square root of a negative number plus the square root of a negative number?

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.)


What is the square root of negative 8?

What is the square root of negative two hundred?

They are +/- 10*sqrt(2)*i where i is the imaginary square root of -1.


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.


How do you get the square root of negative 144?

square root of a negative number is imaginary square root of negative 1 is defined as i square root of negative 144 is sqrt ((144)(-1)) = 12i


What is square root of negative five squared?

The square root of (-5)2 is 5. (-5 is also a square root, but "the" square root refers to the positive root in this case.) The square root of -52 is the square root of -25, or 5i. "i" is the imaginary unit. Read about "imaginary numbers" or "complex numbers" for more information. This would create confusions. Would that mean that the square of any negative number is negative?

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


What 2 numbers would be the square root of 53?

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.

How do you find the negative square root of 5?

How do you find the square root of a negative number?

It is not possible for a negative number to have a square root. Any square root is the number that, when you multiply it by ITSELF it will equal the number you are square rooting. Example: The square root of 4 is 2. 2 times itself(2x2) is 4. Negative numbers are imposable to square root because the square root cannot be multiplied by its opposite ( i.e. -2 times 2 or 4 times -4), it must be multiplied by itself. Any positive multiplied by a positive is a positive, and any negative multiplied by a negative is a positive. So any number times ITSELF will always be a positive. ( i.e. -4 time -4 is 16 as 4 times 4 is also sixteen.) If a squared square root is always positive then a negative number cannot have a square root. It's imposable.* * * * *True for basic mathematics but not so for more advanced mathematics. There is a whole area of mathematics called complex mathematics which is based on the square root of negative numbers. The square root of -1 is defined as i.


Is the square root of negative 5 an integer?

No, it is not even a real number. The square root of negative 5 is the square root of 5, times i.

What is the nonenegative square root of a number?

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.
