Best Answer

Whenever you multiply two numbers, if they have the same sign, then the answer is positive.

When you multiply a number by itself, both numbers in the multiplication obviously have the same sign,

so the answer is positive.

So there's no number that gives a negative answer when you multiply it by itself.

you cant take the square root of a negative number

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

Imaginary number

The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.

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

The square root of a negative number is not real.

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

A negative square root is an imaginary number.

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

No. In general, the square root of a negative number is an imaginary number, which is not a real 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.
