Can you find the square root of a negative number

Answer 1

Remark

Only if you define it into existence. The square root of a negative number is does not exist in the real world.

√(-1) is defined to be i

That is what is termed a complex number.  

Answer 2

No, and therefore, the answer to a negative square root will be "i" which stands for "imaginary" (a group of numbers).

Example:

$\sqrt{-2} = i$
