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. The word "raised" is usually omitted, and sometimes "power" as well, so 3 5 can be simply read "3 to the 5th", or "3 to
In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial.According to the theorem, it is possible to expand the polynomial (x + y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b + c = n, and the coefficient a of each term is a specific positive integer depending ...
A formal power series is a special kind of formal series, of the form. where the called coefficients, are numbers or, more generally, elements of some ring, and the are formal powers of the symbol that is called an indeterminate or, commonly, a variable. Hence, power series can be viewed as a generalization of polynomials, where the number of ...
J.R.R. Tolkien, The Silmarillion, "The Rings of Power and the Third Age" The Rings of Power were forged by the Elven -smiths of the Noldorin settlement of Eregion. [T 1] Best-known were the twenty Great Rings, which conferred powers including invisibility, but many lesser rings with minor powers were also created at that time. The smiths were led by Celebrimbor, the grandson of Fëanor, the ...
A ring is a set R equipped with two binary operations [a] + (addition) and ⋅ (multiplication) satisfying the following three sets of axioms, called the ring axioms: [1] [2] [3] R is an abelian group under addition, meaning that: (a + b) + c = a + (b + c) for all a, b, c in R (that is, + is associative). a + b = b + a for all a, b in R (that ...
Tetration is also defined recursively as. allowing for attempts to extend tetration to non-natural numbers such as real, complex, and ordinal numbers . The two inverses of tetration are called super-root and super-logarithm, analogous to the nth root and the logarithmic functions.
season 2. The second season of the American fantasy television series The Lord of the Rings: The Rings of Power is based on J. R. R. Tolkien 's history of Middle-earth, primarily material from the appendices of the novel The Lord of the Rings. Set thousands of years before the novel in the Second Age of Middle-earth, the season depicts the rise ...
Differential operator. A harmonic function defined on an annulus. Harmonic functions are exactly those functions which lie in the kernel of the Laplace operator, an important differential operator. In mathematics, a differential operator is an operator defined as a function of the differentiation operator. It is helpful, as a matter of notation ...
