    The period of ⁠ c / k ⁠, for c coprime to k, equals the period of ⁠ 1 / k ⁠. If k = 2 a ·5 b n where n > 1 and n is not divisible by 2 or 5, then the length of the transient of ⁠ 1 / k ⁠ is max( a , b ), and the period equals r , where r is the multiplicative order of 10 mod n, that is the smallest integer such that 10 r ≡ 1 (mod ...

  8. Zero to the power of zero - Wikipedia

    en.wikipedia.org/wiki/Zero_to_the_power_of_zero

    Zero to the power of zero, denoted as 0 0, is a mathematical expression that can take different values depending on the context. In certain areas of mathematics, such as combinatorics and algebra, 0 0 is conventionally defined as 1 because this assignment simplifies many formulas and ensures consistency in operations involving exponents.
