In mathematics [ edit] 216 is the cube of 6, and the sum of three cubes: It is the smallest cube that can be represented as a sum of three positive cubes, [1] making it the first nontrivial example for Euler's sum of powers conjecture. It is, moreover, the smallest number that can be represented as a sum of any number of distinct positive cubes ...
As for the number's actual value, 216 is the most frequently ... of Plato's number is 216 because it is the cube of 6, i.e. 6 3 = 216, ... Cubes Equals a Cube ...
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.
Fourth power. In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares. Some people refer to n4 as n “ tesseracted ”, “ hypercubed ”, “ zenzizenzic ...
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 ...
In mathematics. 666 is the sum of the first thirty-six natural numbers, which makes it a triangular number: [4] . Since 36 is also triangular, 666 is a doubly triangular number. [5] Also, 36 = 15 + 21 where 15 and 21 are triangular as well, whose squares ( 152 = 225 and 212 = 441) add to 666 and have a difference of 216 = 6 × 6 × 6.
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
Below are listed the first prime numbers of many named forms and types. More details are in the article for the name. n is a natural number (including 0) in the definitions. Balanced primes. Primes with equal-sized prime gaps between each other, so that they are equal to the arithmetic mean of the nearest primes after and before.
