n. th root. In mathematics, an nth 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. A root of degree 2 is called a square root and a root of degree 3, a cube root.
In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. [ 1][ 2] With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes.
Nested radical. In algebra, a nested radical is a radical expression (one containing a square root sign, cube root sign, etc.) that contains (nests) another radical expression. Examples include. which arises in discussing the regular pentagon, and more complicated ones such as.
A radical ( Chinese: 部首; pinyin: bùshǒu; lit. 'section header'), or indexing component, is a visually prominent component of a Chinese character under which the character is traditionally listed in a Chinese dictionary. The radical for a character is typically a semantic component, though it may be another structural component, or even an ...
In addition, variant characters with identical pronunciation and meaning were reduced to a single standardized character, usually the simplest among all variants in form. Finally, many characters were left untouched by simplification and are thus identical between the traditional and simplified Chinese orthographies.
Adherents. Response to terrorism. v. t. e. Radicalization (or radicalisation) is the process by which an individual or a group comes to adopt increasingly radical views in opposition to a political, social, or religious status quo. The ideas of society at large shape the outcomes of radicalization.
Rationalisation (mathematics) In elementary algebra, root rationalisation is a process by which radicals in the denominator of an algebraic fraction are eliminated. If the denominator is a monomial in some radical, say with k < n, rationalisation consists of multiplying the numerator and the denominator by and replacing by x (this is allowed ...
Radical symbol. In mathematics, the radical symbol, radical sign, root symbol, radix, or surd is a symbol for the square root or higher-order root of a number. The square root of a number x is written as. while the n th root of x is written as. It is also used for other meanings in more advanced mathematics, such as the radical of an ideal .
