Yes. Every perfect square has two roots: one positive and one negative.
A Square Root is one of the two equal factors of a number.
It is: 9900*11 = 108900 which is a perfect square and its square root is 330
The perfect square roots are simply the counting numbers: 1, 2, 3, 4, and so on.The square root of 1 is 1, the square root of 4 is 2, the square root of 9 is 3, the square root of 16 is 4, and so on....See http://www.naturalnumbers.org/psquares.html
And its negative counterpart.
Take the square root of that number. If you get a whole number, the answer is yes; otherwise, the answer is no.
The square root of a negative number is not real.
They are not, other that the fact that any perfect square is a non-negative and so is also a cube root of some non-negative integer (usually much larger). But -2 is a cube root (of -8), while -8 is not a perfect square.
The root of a perfect square will be an integer, but will be both the positive and negative values. For instance, the square root of 4 is plus or minus 2 (±2), as both integral answers are valid. The positive real root is the answer that many books give. It is sometimes called the primary root. But the key point is both roots are valid.
200 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
345 is not a perfect square and neither is its square root.
30 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
500 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
38 is not a perfect square. Its square root is a fraction and the square root of a perfect square is always an integer.
If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
square root of a negative number is imaginary square root of negative 1 is defined as i square root of negative 144 is sqrt ((144)(-1)) = 12i
16 is a perfect square (of 4) and the square root of 256.
