For example, a = B squared.

Then the root of b = the root number a.

The root sign is a symbol used to represent the root operation of a number or an algebra.

If a n = b, then a is the n-th root of b or a is the 1/n power of b.

Open n-th power handwriting and printing are represented by √ ~.

Brief introduction of root number:

The root sign is a mathematical symbol. The root sign is a symbol used to represent the root operation of a number or an algebra. If a? = b, then a is the n-th root of b or a is the 1/n power of b.

N-power handwritten and printed characters are represented by, and the numerical or algebraic expression of the root is written in the area surrounded by the left side of the symbol and the right side of the horizontal part above the symbol, which cannot be crossed.
