This is a simplified list, so the reading of the radical is only given if the kanji is used on its own. Example kanji for each radical are all jōyō kanji, but some examples show all jōyō (ordered by stroke number) while others were from the Chinese radicals page with non-jōyō (and Chinese-only) characters removed.
In number theory, the radical of a positive integer n is defined as the product of the distinct prime numbers dividing n. Each prime factor of n occurs exactly once as a factor of this product: r a d ( n ) = ∏ p ∣ n p prime p {\displaystyle \displaystyle \mathrm {rad} (n)=\prod _{\scriptstyle p\mid n \atop p{\text{ prime}}}p}
歩 consists of Radical 77 止 and 少, and 男 consists of Radical 102 田 and 力. Note that single radical (e.g., Radical 102 田) is used for other type as well, and lesser strokes simple Kanji works as a radical, like 力 is also Radical 19. ashi : 底 Foot element 志 consists of Radical 61 心 and 士, and 畠 consists of Radical 102 田 ...
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 ...
There is one "Yi Radicals" block that includes 55 radicals used to index Yi characters in dictionaries of the standardized Yi script used for writing the Nuosu language in Southern Sichuan and Northern Yunnan. [3] Sets of radicals for other sinoform scripts, such as Jurchen, have also been proposed for encoding in Unicode. [4]
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

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.
