I think it is Xi (whatever the square root of the positive is times i).
i is an imaginary number that when you square it, it becomes negative.
eg. the square root of -4 is 2i. Without "i", it would be impossible to square root a negative number, as any number times itself will always equal a positive.

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.
Why is it impossible to square a negative number?
you can square a negative number but you can not square root a negative 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.)
How do you find the negative square root of 5?
A negative square root is an imaginary number.
How do you get the square root of negative 144?
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
