Cube root. In mathematics, a cube root of a number x is a number y such that y3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted , is 2, because 23 = 8, while the other ...
Cube Route is a fantasy novel by British-American writer Piers Anthony, the twenty-seventh book of the Xanth series. Pangrammatic window. The shortest known published pangrammatic window, a stretch of naturally occurring text that contains all the letters in the alphabet, is found on page 98 of the 2004 First Mass Market Edition.
Doubling the cube, also known as the Delian problem, is an ancient [a] [1] : 9 geometric problem. Given the edge of a cube, the problem requires the construction of the edge of a second cube whose volume is double that of the first. As with the related problems of squaring the circle and trisecting the angle, doubling the cube is now known to ...
if a has a cube root in K, there exists a unique b such that a = b 3.Otherwise, it is necessary to consider an extension field of K (e.g., K(a 1/3)). Then, since b 3 · x 3 = bx 3, defining t = b · x, the following equation is needed (in Hessian form) to do the transformation: + + =.

An illustration of an unsolved Rubik's Cube. The Rubik's Cube is a 3D combination puzzle invented in 1974 [2] [3] by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, [4] the puzzle was licensed by Rubik to be sold by Pentangle Puzzles in the UK in 1978, [5] and then by Ideal Toy Corp in 1980 [6 ...
For any given choice of cube root and its conjugate, this contains nested radicals involving complex numbers, yet it is reducible (even though not obviously so) to one of the solutions 1, 2, or –3. Infinitely nested radicals Square roots. Under certain conditions infinitely nested square roots such as
