  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. 64 (number) - Wikipedia

    en.wikipedia.org/wiki/64_(number)

    the number of vertices in a 6-cube, the fourth dodecagonal number, [8] and the seventh centered triangular number. [9] Since it is possible to find sequences of 65 consecutive integers (intervals of length 64) such that each inner member shares a factor with either the first or the last member, 64 is the seventh Erdős–Woods number. [10]

  4. Sixth power - Wikipedia

    en.wikipedia.org/wiki/Sixth_power

    64 (2 6) and 729 (3 6) cubelets arranged as cubes ((2 2) 3 and (3 2) 3, respectively) and as squares ((2 3) 2 and (3 3) 2, respectively) In arithmetic and algebra the sixth power of a number n is the result of multiplying six instances of n together. So: n 6 = n × n × n × n × n × n.

  5. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    Similarly, the expression b 3 = b · b · b is called "the cube of b" or "b cubed", because the volume of a cube with side-length b is b 3. When an exponent is a positive integer, that exponent indicates how many copies of the base are multiplied together. For example, 3 5 = 3 · 3 · 3 · 3 · 3 = 243.

  6. Seventh power - Wikipedia

    en.wikipedia.org/wiki/Seventh_power

    In arithmetic and algebra, the seventh power of a number n is the result of multiplying seven instances of n together. So: n 7 = n × n × n × n × n × n × n.. Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.

  7. 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:

    The siriometer is an obsolete astronomical measure equal to one million astronomical units, i.e., one million times the average distance between the Sun and Earth. [13] This distance is equal to about 15.8 light-years, 149.6 Pm, or 4.8 parsecs, and is about twice the distance from Earth to the star Sirius. [14]

  9. 1728 (number) - Wikipedia

    en.wikipedia.org/wiki/1728_(number)

    1728 is an abundant and semiperfect number, as it is smaller than the sum of its proper divisors yet equal to the sum of a subset of its proper divisors. [ 11 ] [ 12 ] It is a practical number as each smaller number is the sum of distinct divisors of 1728, [ 13 ] and an integer-perfect number where its divisors can be partitioned into two ...
