Determine the square root of  -324.

The given is a negative number, and it is a general rule that negative numbers do not have a square root, since square root can only be positive or negative. To further understand this, whenever a number is squared, the answer will be positive, since similar signs will yield a positive answer.  In taking the square of a negative number, we will have “i” which represents it as an imaginary number, and not a real number.

=√-324

= -18i
