    Graphs of y = b x for various bases b: base 10, base e, base 2, base ⁠ 1 / 2 ⁠. Each curve passes through the point (0, 1) because any nonzero number raised to the power of 0 is 1. At x = 1, the value of y equals the base because any number raised to the power of 1 is the number itself.

  3. Fifth power (algebra) - Wikipedia

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

    In arithmetic and algebra, the fifth power or sursolid [1] of a number n is the result of multiplying five instances of n together: n 5 = n × n × n × n × n. 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:

  4. Power of two - Wikipedia

    en.wikipedia.org/wiki/Power_of_two

    The first 3 powers of 2 with all but last digit odd is 2 4 = 16, 2 5 = 32 and 2 9 = 512. The next such power of 2 of form 2 n should have n of at least 6 digits. The only powers of 2 with all digits distinct are 2 0 = 1 to 2 15 = 32 768, 2 20 = 1 048 576 and 2 29 = 536 870 912.

  5. Multiset - Wikipedia

    en.wikipedia.org/wiki/Multiset

    An indexed family (a i) i∈I, where i varies over some index set I, may define a multiset, sometimes written {a i}. In this view the underlying set of the multiset is given by the image of the family, and the multiplicity of any element x is the number of index values i such that =. In this article the multiplicities are considered to be ...

  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.

    A partition of a set is defined as a family of nonempty, pairwise disjoint subsets of whose union is . For example, B 3 = 5 {\displaystyle B_{3}=5} because the 3-element set { a , b , c } {\displaystyle \{a,b,c\}} can be partitioned in 5 distinct ways:
