It depends on the level that you are at.
For more advanced mathematics, the square root of -1 is a number, denoted by i. It is a basic element of complex numbers and is called the imaginary root of -1.

∙ 12y agoThere are no real answers for a square root of a negative number. Try it on a good scientific calculator (some calculators simply square root the positive, ignoring the negative input), and it should come up with a math error.
"i" is the square root of -1. Since there is no real number whose square is negative, i is an imaginary number.
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
Shorthand for "square root" and can also refer to cube root ("third root") etc etc.

The principal square root is the non-negative square root.
The square root of negative 64 isn't even a real number. In math and engineering, it's called an "imaginary number".

That greatly depends on what level of math you are taking. Early math classes might want you to say, "You can't take the square root of a negative number." Later math will talk about real numbers and still the answer would be, "The square root of -4 does not have a real answer." Still later in your math career you will see imaginary numbers whereby the special character "i" is equivalent the the square root of -1. If imaginary answers are allowed, then the square root of -4 = 2i (since -4 is the same as -1 x 4, the square root of -1 x 4 = i x 2 =2i)
i = the square root of negative one

No negative number can have a real square root.In math and engineering, the symbol ' i ' is used to representthe square root of -1 .Then the square root of -19 can be written as 4.3589 i (rounded).
The square root of negative 37 is: ~6.0827 i
The square root of negative 168 is: ~12.9315 i
