Nth Root Formula:

ⁿ√x = y where yⁿ = x

This means y multiplied by itself n times equals x

Alternative notation: ⁿ√x = x^(1/n)

Example: ∛1728 = 12, because 12³ = 12 × 12 × 12 = 1728

Even roots: For even n, the root of negative numbers yields complex results

Odd roots: For odd n, ⁿ√(-x) = -(ⁿ√x)
