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 ...
History. The route was created in 1922, running from Williamston to Rich Square. The section between Scotland Neck and Rich Square was rerouted in 1925; the northern terminus of NC 125 was moved near Halifax. In 1965 the route was expanded northwards, replacing several secondary routes, to end at US 158 in Roanoke Rapids.
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.
A Hamiltonian path or traceable path is a path that visits each vertex of the graph exactly once. A graph that contains a Hamiltonian path is called a traceable graph. A graph is Hamiltonian-connected if for every pair of vertices there is a Hamiltonian path between the two vertices. A Hamiltonian cycle, Hamiltonian circuit, vertex tour or ...
New Hampshire Route 125 is a 51.994-mile-long (83.676 km) north–south state highway in Rockingham, Strafford and Carroll counties in southeastern New Hampshire. The southern terminus is in Plaistow at the Massachusetts state line, where the road continues south into Haverhill as Massachusetts Route 125. The northern terminus is in Wakefield ...
Route 125 begins at an intersection with Route 4 in the town center of Cornwall and heads north for 1.2 miles (1.9 km) to end at an intersection with Route 128. Route 125 is known as Grange Hill Road and is a short connector between Route 4, which leads to the village of Cornwall Bridge, and Route 128, which leads to the village of West Cornwall.
125 is the cube of 5 . It can be expressed as a sum of two squares in two different ways, 125 = 10² + 5² = 11² + 2². [1] 125 and 126 form a Ruth-Aaron pair under the second definition in which repeated prime factors are counted as often as they occur. Like many other powers of 5, it is a Friedman number in base 10 since 125 = 5 1 + 2 .
Initially conceived as a 0.125 mi (0.201 km) drag strip, the track was extended to a full 0.250 mi (0.402 km) in 1971. Having been developed on dormant swampland that was long ago buried by the Mississippi River, the track soon adapted the nickname of "The Swamp". Throughout the 1970s, the raceway primarily held regional drag racing events.
