Worked example: Cube root of a negative number, Practice: Equations with square roots & cube roots, Practice: Equations with square roots: decimals & fractions. The difference between any perfect square and its predecessor is given by the identity n 2 − (n − 1) 2 = 2n − 1.Equivalently, it is possible to count square numbers by adding together the last square, the last square's root, and the current root, that is, n 2 = (n − 1) 2 + (n − 1) + n. Properties. The side length of the square region is the square root of the perfect square. No one actually knows who invented the square root, but it is thought that the knowledge of square roots originally came from dividing areas of land into equal parts so that the length of the side of a square became the square root of its area. Revealing properties of perfect squares Prof Brown has observed that some properties of perfect squares are revealed if the numbers are expressed in a base that is a power of 2, such as in the binary, octal and hexadecimal number systems.
