In the case of two nested square roots, the following theorem completely solves the problem of denesting. [2]If a and c are rational numbers and c is not the square of a rational number, there are two rational numbers x and y such that + = if and only if is the square of a rational number d.
A solution in radicals or algebraic solution is an expression of a solution of a polynomial equation that is algebraic, that is, relies only on addition, subtraction, multiplication, division, raising to integer powers, and extraction of n th roots (square roots, cube roots, etc.). A well-known example is the quadratic formula
Notation for the (principal) square root of x. For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 5 2 (5 squared). In mathematics, a square root of a number x is a number y such that =; in other words, a number y whose square (the result of multiplying the number by itself, or ) is x. [1]
In mathematics, in the theory of modules, the radical of a module is a component in the theory of structure and classification. It is a generalization of the Jacobson radical for rings . In many ways, it is the dual notion to that of the socle soc( M ) of M .
In mathematics, an n th root of a number x is a number r (the root) which, when raised to the power of the positive integer n, yields x: = ⏟ =.. The integer n is called the index or degree, and the number x of which the root is taken is the radicand.
This result also holds for equations of higher degree. An example of a quintic whose roots cannot be expressed in terms of radicals is x 5 − x + 1 = 0. Some quintics may be solved in terms of radicals. However, the solution is generally too complicated to be used in practice.
The fixed rate for a 15-year mortgage is 5.84%, down 12 basis points from last week's average 5.96%. These figures are lower than a year ago, when rates averaged 6.95% for a 30-year term and 6.38% ...
The radical of an algebraic group is the identity component of its maximal normal solvable subgroup.For example, the radical of the general linear group (for a field K) is the subgroup consisting of scalar matrices, i.e. matrices () with = = and = for .
