The square root of a number which when multiplied by itself gives the original number.
eg √4 = 2 since 2 × 2 = 4.
As a negative times a negative is positive, there are two square roots for every positive number: 2 × 2 = -2 × -2 = 4 so both 2 and -2 as the square roots of 4. Also, negative numbers do not have square roots (that are real numbers*)
By convention/definition the radical symbol (√) is used to denote the positive square root.
* Negative numbers have square roots that are complex numbers. These numbers have a real bit and an imaginary bit, and are of the form (a + bi) where a and b are real numbers and i is used to denote the square root of -1 (except in electrical engineering where the little 'i' is used to denote small currents so the little 'j' is used instead); thus: i² = -1.
eg √-4 = √(4 × -1) = √4 √-1 = 2 √-1 = 2i
squaring: (2i)² = 2² × i² = 4 × -1 = -4.

What is the negative square root of 324?
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.
What does root mean in math?

What is the square root of negative 4?
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)
What is another word for the square root symbol?
A radical. Math is √!
