Algorithm under root sign

Radical number and algorithm: conditions: a≥0, n≥2, n ∈ n. conditions: a≥0, n≥2, n ∈ n. conditions: a≥0, b>0, n≥2 and n ∈ n. conditions: a≥0, n.

Property: In the range of real numbers: (1) Even numbers cannot be negative, and its operation result is not negative.

(2) It can be negative under odd root sign. Not limited to real numbers, that is, when considering imaginary numbers, even roots can be negative numbers, and i=√- 1 can be used.

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.
