the square root of 1 is 1. The square root of -1 is j (if you are an engineer) or i (if you are a math geek)
The negative square root of 324 is -18. In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. Since the square root of 324 is 18, the negative square root would be -18.
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)
