345 is not a perfect square and neither is its square root.
Any integer is a perfect square oot (of its square). So 300 is a perfect square root of 90000.
The square root of negative 40 is: 6.324555 i
Yes, a perfect square is a number that has an integer square root.
The idea is to take out perfect squares. The largest perfect square in this case is 256, which is the square of 16 (if you have trouble figuring this out, you can take out a smaller perfect square first, and then see if you find additional perfect squares). In any case, the end result should not have a factor that is a perfect square. Using the symbol "root()" for square root: root(512) = root(256 x 2) = root(256) x root(2) = 16 root(2)
The square root of a negative number is not real.
Yes. Every perfect square has two roots: one positive and one negative.
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.
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.
