  2. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    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. The base 3 appears 5 times in the multiplication, because the exponent is 5. Here, 243 is the 5th power of 3, or 3 raised to the 5th power.

  3. Legendre's formula - Wikipedia

    en.wikipedia.org/wiki/Legendre's_formula

    As one special case, it can be used to prove that if n is a positive integer then 4 divides () if and only if n is not a power of 2. It follows from Legendre's formula that the p -adic exponential function has radius of convergence p − 1 / ( p − 1 ) {\displaystyle p^{-1/(p-1)}} .

    Yao's method collects in u first those x i that appear to the highest power ⁠ ⁠; in the next round those with power ⁠ ⁠ are collected in u as well etc. The variable y is multiplied ⁠ h − 1 {\displaystyle h-1} ⁠ times with the initial u , ⁠ h − 2 {\displaystyle h-2} ⁠ times with the next highest powers, and so on.

  5. Sums of powers - Wikipedia

    en.wikipedia.org/wiki/Sums_of_powers

    In mathematics and statistics, sums of powers occur in a number of contexts: . Sums of squares arise in many contexts. For example, in geometry, the Pythagorean theorem involves the sum of two squares; in number theory, there are Legendre's three-square theorem and Jacobi's four-square theorem; and in statistics, the analysis of variance involves summing the squares of quantities.

    f is continuous at any one point (Rudin, 1976, chapter 8, exercise 6). f is increasing on any interval. For the uniqueness, one must impose some regularity condition, since other functions satisfying f ( x + y ) = f ( x ) f ( y ) {\displaystyle f(x+y)=f(x)f(y)} can be constructed using a basis for the real numbers over the rationals , as ...
