The square root of a negative value is called an imaginary 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.
No, it is a complex number.
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.
Neither. (It is a complex number.)
They are called real numbers. Negative square roots must be complex numbers.
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.
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.
No, it is a complex number.
The negative square root of -144 is -12i - that is -12 times the square root of minus 1, ie √-144 = 12√-1.

Neither. (It is a complex number.)
You can, if you consider complex numbers.
They are called real numbers. Negative square roots must be complex numbers.
Complex numbers are the square roots of negative numbers. i.e. root -1 = i
The square root of 100 is rational since it is not repeating.
The "i" part is the imaginary square root of negative one.
No. It is a complex number, but that is something different.
No, it is an imaginary number which is a complex number.
