The root number of extended data 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.

Formula for calculating the root sign:

①

Conditions: a≥0, n≥2, n ∈ n

②

Conditions for establishment: a≥0, b≥0, n≥2, n ∈ n

③

Conditions for establishment: a≥0, b>0, n≥2 and n ∈ n

④

Conditions for establishment: a≥0, b>0, n≥2 and n ∈ n
