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
A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...
If we solve this equation, we find that x = 2. More generally, we find that + + + + is the positive real root of the equation x 3 − x − n = 0 for all n > 0. For n = 1, this root is the plastic ratio ρ, approximately equal to 1.3247.
In elementary algebra, root rationalisation (or rationalization) 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, as, by definition, a n th root of x is a number that ...
An unresolved root, especially one using the radical symbol, is sometimes referred to as a surd [2] or a radical. [3] Any expression containing a radical, whether it is a square root, a cube root, or a higher root, is called a radical expression , and if it contains no transcendental functions or transcendental numbers it is called an algebraic ...
Radical 16 or radical table (几部), meaning small table, is one of 23 of the 214 Kangxi radicals that are composed of 2 strokes. 几 is also the 16th indexing component in the Table of Indexing Chinese Character Components predominantly adopted by Simplified Chinese dictionaries published in mainland China .
Radical 162 or radical walk (辵部) meaning "walk" is one of the 20 Kangxi radicals (214 radicals in total) composed of 7 strokes. When used as a component, this radical character transforms into ⻍, ⻌, or ⻎ (See #Variant forms). In the Kangxi Dictionary, there are 381 characters (out of 49,030) to be found under this radical.
Radical 108 or radical dish (皿部) meaning "dish" is one of the 23 Kangxi radicals (214 radicals in total) composed of 5 strokes. In the Kangxi Dictionary , there are 129 characters (out of 49,030) to be found under this radical .
