Kuinka laskea Nth Root
Mikä on Nth Root?
The nth root of a number x is the value r such that rⁿ = x. The square root is the 2nd root; cube root is the 3rd root. For even roots of negative numbers, no real solution exists (result is a complex number).

- x^(1/3) — x^(1/3)
Vaiheittainen opas
- 1ⁿ√x = x^(1/n)
- 2Square root: ²√x = x^0.5
- 3Cube root: ³√x = x^(1/3)
- 4Nth root: use x^(1/n) on a calculator
- 5Negative numbers: odd roots are fine (³√−8 = −2); even roots are complex
