The root sign is a mathematical symbol, and the root sign is a symbol used to represent the root operation of a number or an algebraic expression. If a? =b, then a is the n-th root of b or a is the 1/n power of b.
N-th power handwriting and printing are represented by n √, and the number of roots or algebraic expressions are written in the area surrounded by the left and right √ of the symbol and the lower part of a horizontal part above the symbol, which cannot be out of bounds.
Radical solution polynomial
It has been suspected that all roots of polynomials can be expressed by root signs and basic operations; But Abel-Ruffini theorem asserts that this is not universally true. For solving any equation of degree n, please refer to the root algorithm.
