Can a perfect square have a negative root
WebA perfect square is an integer that can be expressed as the product of two equal integers. For example, 100 100 is a perfect square because it is equal to 10\times 10 10× 10. If N N is an integer, then N^2 N 2 is a perfect square. Because of this definition, perfect squares are always non-negative. WebNegative numbers doesn't have real square roots since a square is either positive or 0. If the square root of an integer is another integer then the square is called a perfect square.
