Brief facts about cubed:
In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 2³ = 8 or³. The cube is also the number multiplied by its square: The cube function is the function x ↦ x³ that maps a number to its cube. It is an odd function, as The volume of a geometric cube is the cube of its side length, giving rise to the name. The inverse operation that consists of finding a number whose cube is n is called extracting the cube root of n. It determines the side of the cube of a given volume. It is also n raised to the one-third power. The graph of the cube function is known as the cubic parabola. Because the cube function is an odd function, this curve has a center of symmetry at the origin, but no axis of symmetry.
Cabtaxi number - In number theory, the n-th cabtaxi number, typically denoted Cabtaxi, is defined as the smallest positive integer that can be written as the sum of two positive or negative or 0 cubes in n ways. Such numbers exist for all n, which follows from the analogous result for taxicab numbers.
Cubic equation - In algebra, a cubic equation in one variable is an equation of the form :ax^3+bx^2+cx+d=0 in which is nonzero.
Doubling the cube - Doubling the cube, also known as the Delian problem, is an ancient 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.
Eighth power - In arithmetic and algebra the eighth power of a number n is the result of multiplying eight instances of n together. So: Eighth powers are also formed by multiplying a number by its seventh power, or the fourth power of a number by itself.
Euler's sum of powers conjecture - Euler's conjecture is a disproved conjecture in mathematics related to Fermat's Last Theorem. It was proposed by Leonhard Euler in 1769.
Fifth power - In arithmetic and algebra, the fifth power or sursolid of a number n is the result of multiplying five instances of n together: Fifth powers are also formed by multiplying a number by its fourth power, or the square of a number by its cube. The sequence of fifth powers of integers is...
