The square root of a negative number is considered an imaginary number. In this case, the square root of -2 is represented as √(-2) = √2i, where i is the imaginary unit equal to the square root of -1. This is because the square root of -1 is not a real number, so we introduce the concept of imaginary numbers to handle such cases in mathematics.

SteveYou would get (i square root 2) because you can not square root a negative number, the answer is imaginary.
Tmdkiller: Square root is NOT applicable to any Negative numbers eg -1 ,-2,-3 etc
You would get an "Error 2" on a scientific Calculator anyway. =)

squre root of -2 is 2i (where "i" is "iota" represents imaginary or complex number......

What is the square root of negative 18 in radical form?
The square root of negative 18 is an imaginary number.The square root of positive 18 is [ 3 sqrt(2) ].If the 18 is negative, then scientists and engineers indicate its square root as 3i sqrt(2) . The little ' i ' indicates the square root of negative one.
What is the square root of negative pi?
Answer 1:The only answer is π^-1iThe square root of -1 is i so i times the square root of pi is equal to the square root of negative piAnswer 2:More concretely, the square root of negative pi is approximately 1.772453850905i, wherein the 1.772453850905 represents an approximation of pi, and "i", which should be a lower case cursive "i", represents the square root of negative one.
What is the nonenegative square root of a number?
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.
What is the symbol used to represent a negative square root of a number?
Negative square root is -√Square root of negative one is i.
What is the nonnegative square root of a number?
Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.
