    [2] [3] [4] It is equivalent to ⁠ 1 / 400 ⁠ of a turn, [5] ⁠ 9 / 10 ⁠ of a degree, or ⁠ π / 200 ⁠ of a radian. Measuring angles in gradians (gons) is said to employ the centesimal system of angular measurement, initiated as part of metrication and decimalisation efforts.

  4. Power residue symbol - Wikipedia

    en.wikipedia.org/wiki/Power_residue_symbol

    In algebraic number theory the n-th power residue symbol (for an integer n > 2) is a generalization of the (quadratic) Legendre symbol to n-th powers. These symbols are used in the statement and proof of cubic , quartic , Eisenstein , and related higher [ 1 ] reciprocity laws .

  5. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    Where a power of ten has different names in the two conventions, the long scale name is shown in parentheses. The positive 10 power related to a short scale name can be determined based on its Latin name-prefix using the following formula: 10 [(prefix-number + 1) × 3] Examples: billion = 10 [(2 + 1) × 3] = 10 9; octillion = 10 [(8 + 1) × 3 ...

  6. Fourth power - Wikipedia

    en.wikipedia.org/wiki/Fourth_power

    n 4 = n × n × n × n. 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 ...

    It is clear that 16 is not a 2-adic 8th power, and hence not a rational 8th power, since the 2-adic valuation of 16 is 4 which is not divisible by 8. Generally, 16 is an 8th power in a field K if and only if the polynomial X 8 − 16 {\displaystyle X^{8}-16} has a root in K .

  8. Sixth power - Wikipedia

    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. Sixth powers can be formed by multiplying a number by its fifth power, multiplying the square of a number by its fourth power, by cubing a square, or by squaring a cube.

  9. Graph power - Wikipedia

    Alternatively, If A is an adjacency matrix for the graph, modified to have nonzero entries on its main diagonal, then the nonzero entries of A k give the adjacency matrix of the k th power of the graph, [14] from which it follows that constructing k th powers may be performed in an amount of time that is within a logarithmic factor of the time ...
