Understanding your result
Read result in the units and model stated on this page. The formula result=x<0 ? -abs(x)^(1/n) : x^(1/n) defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
