How it works
ⁿ√x = x^(1/n)Frequently Asked Questions
How do I calculate an nth root without a root button?
Raise to the reciprocal power: the 5th root of 32 is 32^(1/5) = 2. That identity is exactly what this calculator (and every scientific calculator) uses.
Can you take the root of a negative number?
Odd roots yes (∛−27 = −3); even roots of negatives have no real answer — they live in the complex numbers as imaginary results.
What is the square root of 2?
About 1.41421356 — an irrational number whose decimals never repeat, famous as the first number proven irrational.
