  2. Cube (algebra) - Wikipedia

    en.wikipedia.org/wiki/Cube_(algebra)

    The cube of a number n is denoted n 3, using a superscript 3, [a] for example 2 3 = 8. The cube operation can also be defined for any other mathematical expression, for example (x + 1) 3. The cube is also the number multiplied by its square: n 3 = n × n 2 = n × n × n. The cube function is the function x ↦ x 3 (often denoted y = x 3) that

  3. Cube root - Wikipedia

    en.wikipedia.org/wiki/Cube_root

    In mathematics, a cube root of a number x is a number y that has the given number as its third power; that is =. The number of cube roots of a number depends on the number system that is considered. Every nonzero real number x has exactly one real cube root that is denoted x 3 {\textstyle {\sqrt[{3}]{x}}} and called the real cube root of x or ...

  4. 8 - Wikipedia

    en.wikipedia.org/wiki/8

    By Mihăilescu's Theorem, it is the only nonzero perfect power that is one less than another perfect power. 8 is the first proper Leyland number of the form x y + y x, where in its case x and y both equal 2. [4] 8 is a Fibonacci number and the only nontrivial Fibonacci number that is a perfect cube. [5] Sphenic numbers always have exactly eight ...

  6. Fourth power - Wikipedia

    en.wikipedia.org/wiki/Fourth_power

    Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares. Some people refer to n 4 as n tesseracted, hypercubed, zenzizenzic, biquadrate or supercubed instead of “to the power of 4”. The sequence of fourth powers of integers, known as biquadrates or tesseractic numbers, is:

  8. nth root - Wikipedia

    en.wikipedia.org/wiki/Nth_root

    Every non-zero number x, real or complex, has n different complex number nth roots. (In the case x is real, this count includes any real nth roots.) The only complex root of 0 is 0. The nth roots of almost all numbers (all integers except the nth powers, and all rationals except the quotients of two nth powers) are irrational. For example,

  9. 1729 (number) - Wikipedia

    en.wikipedia.org/wiki/1729_(number)

    Visually, 1729 can be found in other figurate numbers. It is the tenth centered cube number (a number that counts the points in a three-dimensional pattern formed by a point surrounded by concentric cubical layers of points), the nineteenth dodecagonal number (a figurate number in which the arrangement of points resembles the shape of a ...
