its called a "perfect square"
Actually a negative number can be under a square root symbol. This becomes very useful in electrical calculations. The square root of -1 is j. That is, j2 = -1.
The radicand.
Multiplying a number by itself is called "squaring". Ex. "What is the square of 5?" Answer: 25 And when you calculate, from the square (25) what the original number was, it is called "finding the square root." Ex. "What is the square root of 25?" Answer: 5.
The square root of a negative value is called an imaginary number.

False
Simply put :3 If you want to know more The square root of a number is the positive number that squared will give the number under the square root

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
A perfect square.
The square of that integer.
It can be an exponent (if you find it after your number) or a root (if you find it in the bend of the square root sign. In the square root sign that goes over a number, if there is nothing in the bend (or the "V") of the sign, then the sign indicates the square root of the number under the "roof" of the sign. If there IS a number in the "V", for instance 3, it means the cube root of the number under the roof; a 4 in the V means the fourth root, and so on. Think of a number under the roof of the square root sign as yielding the opposite value from the same number with an exponent of 2. If you put a number with an exponent of 2 under a square root sign, the result will be your original number: in other words, the square root of 2 squared is 2. If you want to express a square root without the square root sign, you could simply give your number an exponent of the RECIPROCAL of two (e.g. 9-1/2), which equals 3. In words, this means nine to the one-half power equals the square root of nine, equals 3.x2 -- the 2 is called a subscript which here means the second value of x, usually after being changed by a function, or perhaps it indicates the second value of x that will be used in your calculationx2 -- the 2 is called a superscript (or "power") which here means x to the second power (x squared).
simply see what you can multiply twice to get the number under the square root sign.
