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.

How do you find the negative square root of 5?
A negative square root is an imaginary number.
How do you find the square root of a negative number ie sqrt of 0.6?
There is no need to find the square root of a negative number for sqrt(0.6)!
How do you find the two square roots in a number?
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.
Why cant you evaluate the square root of negative twenty five using real numbers?
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
How do you do a square root of a negative number that is not a perfect square?
The square root of a negative number is not real.
How do you find the negative square root of 5?
A negative square root is an imaginary number.
How would you find the square root of negative 1?
One cannot find the square root of a negative number.
How do you find the square root of a negative number ie sqrt of 0.6?
There is no need to find the square root of a negative number for sqrt(0.6)!
Find the Square Root -81?
There is no square root for a negative number. It is an imaginary number.
How do you find the two square roots in a number?
Use a calculator (if you need) to find the principal square root. The second square root is the negative of the number.

How do you do a square root of a negative number that is not a perfect square?
The square root of a negative number is not real.
What is the square root of -10?
You can't find the square root of -10 because you can't find the square root of any negative number. But we have something to represent the answer, i, i is a imaginary 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
How do you find negative square root of 49?
You don't. If the negative sign is outside the radical, then you take the square root of the number and apply the negative. If the negative sign is inside the radical, you will have an imaginary number.
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.)
Why is it possible to find a real cube root of a negative number but not a real square root of a negative number?
You cannot get real square root of a negative number because two numbers multiplied by themselves are always positive You can always get a real cube root of a negative number because three negative numbers multiplied by themselves give a negative .
