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.
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.
Most common radicals. There are two readings for a kanji: On'yomi and Kun'yomi. On'yomi is a reading derived from the Chinese way of reading, Kun'yomi is the original Japanese reading. The six radicals that occur the most frequently [2] (in order of frequency) [3] and make up 25% of the 2136 Jōyō kanji: 口 (くち) (3 strokes)
Radical 64 or radical hand (手部) meaning "hand" is one of the 34 Kangxi radicals (214 radicals in total) composed of 4 strokes. When appearing as a left-side component, this radical is almost always written as 扌 (notable exceptions: 拜 , although Japanese shinjitai analogizes it to 拝 ; and dialectal characters 掰, 搿), while it ...
Quadratic formula. The roots of the quadratic function y = 1 2 x2 − 3x + 5 2 are the places where the graph intersects the x -axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
Radical 140 or radical grass (艸部) meaning " grass " is one of 29 of the 214 Kangxi radicals that are composed of 6 strokes. It transforms into 艹 when appearing at the top of a character or component. In the Kangxi Dictionary and in modern standard Traditional Chinese as used in Taiwan, Hong Kong and Macau, 艹 (with two horizontal strokes ...
Plot of the Bring radical for real argument. In algebra, the Bring radical or ultraradical of a real number a is the unique real root of the polynomial. The Bring radical of a complex number a is either any of the five roots of the above polynomial (it is thus multi-valued), or a specific root, which is usually chosen such that the Bring ...
A solution in radicals or algebraic solution is a closed-form expression, and more specifically a closed-form algebraic expression, that is the solution of a polynomial equation, and relies only on addition, subtraction, multiplication, division, raising to integer powers, and the extraction of n th roots (square roots, cube roots, and other integer roots).
