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 ...
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 ...
Pennsylvania Route 512 ( PA 512) is a 26.1-mile-long (42.0 km) state route in Northampton County in the Lehigh Valley region in eastern Pennsylvania. The southern terminus is at U.S. Route 22 (US 22) north of Bethlehem in Hanover Township. The northern terminus is at PA 611 in Upper Mount Bethel Township. The route heads north from US 22 to ...
The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3 . The cube is also the number multiplied by its square : n3 = n × n2 = n × n × n. The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as.

The St. Clair route became the first to have an underground connection with the subway. April 16, 1980 The Canadian Light Rail Vehicle started revenue service on the St. Clair route. At about this time, the route received the 512 number, and the Earlscourt route, which was a shortened version of the St. Clair route, was folded into 512 St. Clair.
A three-dimensional model of a figure-eight knot.The figure-eight knot is a prime knot and has an Alexander–Briggs notation of 4 1.. Topology (from the Greek words τόπος, 'place, location', and λόγος, 'study') is the part of mathematics concerned with the properties of a geometric object that are preserved under continuous deformations, such as stretching, twisting, crumpling, and ...
