About Root Calculator
The nth root of a number X is a value that, when raised to the power N, gives X. For example, the cube root of 27 is 3, since 3³ = 27. For even roots (like square root), the radicand must be non-negative. For odd roots (like cube root), negative numbers are allowed: ³√(-8) = -2.
