Because for a number to be a square number it must have a number which when multiplied by it self=that number. For example: 36 is a square number because 6x6=36 16 is a square number because 4x4=16 A negative number such as -16 is not a Square Number because -4x-4=16 not -16 because a negative times a negative is a positive. -4x4=-16 but these numbers aren't the same therefore -16 isn't a square number. This is why negative numbers cant be Square Numbers
Imaginary number
The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.
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.
It is a negative whole number or integer in the form of -49
you can square a negative number but you can not square root a negative number
The square root of a negative number is not real.
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.
The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.
No. In general, the square root of a negative number is an imaginary number, which is not a real number.
It is positive.

Imaginary number
If you're referring to the square root of a negative number, it's an imaginary number.
Negative the square root of 36 is -6, which is a whole number.
Positive.
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
