Can you square an integer and get a negative number?

No. The square of a positive number is positive; the square of a negative number is also positive; and the square of zero is zero. If you want to square a number and get a negative result, you need complex numbers. For example, the square of 2i is -4.


Is the square root of negative 195 rational?

No, it is a complex number.


Is the square root a real number?

The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.


What are positive square roots called?

They are called real numbers. Negative square roots must be complex numbers.


Where you use complex number?

Complex numbers are the square roots of negative numbers. i.e. root -1 = i


Is the square root of -100 rational?

No. The square root of a negative number is not a real number, but an imaginary number, because no real number squared equals a negative number.


Is the square root of negative 64 irrational?

No. It is a complex number, but that is something different.


What is the i part of a complex number?

The "i" part is the imaginary square root of negative one.


Can you take the square root of a negative number?

You can, if you consider complex numbers.


Is the square root of negative 127 an irrational or rational number?

Neither. (It is a complex number.)


Why is it impossible to square a negative number?

you can square a negative number but you can not square root a negative number


Square root of a negative number?

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


What happens when you square root a negative number?

The square root of a negative number is not real. However, there is a field of numbers known as the complex number field which contains the reals and in which negative numbers have square roots. Complex numbers can all be expressed in the form a+bi where a and b are real and i is the pure imaginary such that i2=1. Please see the related links for more information about complex and imaginary numbers.


What is an unreal number?

Imaginary and complex numbers are an extension of the Real Number system. They are not called unreal. An imaginary number is a non-existent number, like the square root of a negative number. For example, the square root of -4 is 2i (i stands for imaginary). There are also complex numbers, which are defined as the sum of a real number and an imaginary number (e.g. 4 + 3i). An imaginary number does not exist, but can nevertheless be useful in certain applications. An imaginary number is any number that is the product of a real number and the square root of negative one (-1). The square root of -1 is the "unit" of the set of imaginary numbers, and is referred to as "i". As you know, negative numbers cannot have square roots, and so the square root of any negative number is "imaginary". There are also "complex numbers", which are the sum of a real number and an imaginary number. For example 3 + 2i.


What is the negative square root of -144?

The negative square root of -144 is -12i - that is -12 times the square root of minus 1, ie √-144 = 12√-1. The above is a complex number, which I suspect is not the answer you wanted; there is no real number that is the square root of a negative number If you wanted the negative square root of 144, then it is -12.


Is the square root of negative two an irrational number?

No, it is an imaginary number which is a complex number.


Is there a number that doesn't have a square root?

Any negative number, and infinity. However, a number (called "i") was created to represent the square roots of negative numbers.


What is the number i?

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.


Is the square root of -25 irrational or complex?

you cant get the square root of a negative number. nothing times itself would equal a negative number. if you have √-25 then its not possible. If you have -√25 then you take the square root of 25 and make it negative, so then it would be -5


Is the square root of negative 6 irrational?

No, it is not irrational because it is a square root of a negative number - which falls into the set of Complex numbers. Irrational numbers can not have an imaginary component.


Is the square root of negative 1 irrational?

No, it is neither rational nor irrational. It is a complex number.


Can a negative number be inside a square root?

Yes. But until you study complex numbers, there is no solution.


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.)


Is the square root of 24 real complex or imaginary?

The square root of any positive real number (as in this case) is a real number. (Such square roots are usually irrational.)The square root of a negative real number, such as the square root of -15, is an imaginary, and therefore also a complex, number.


If you divide 4 by the square root of -7 and then times that by the square root of sin30 how many swag points will you gain?

I am not sure what you want to calculate; anyway, the square root of a negative number is a complex number: in this case, "i" multiplied by the square root of 7. The remaining calculations will also result in complex numbers. When you calculate points, you usually want a real number, not a complex number.
