Questions Fréquentes
What is an nth root?
The nth root of a number x is the value that, when multiplied by itself n times, equals x. For example, the 4th root of 16 is 2 because 2⁴ = 16.
How is nth root related to exponents?
Taking the nth root is the same as raising to the power 1/n. So ⁿ√x = x^(1/n).
Can you take the nth root of a negative number?
For odd values of n, yes. For example, ∛(-8) = -2. For even values of n, the nth root of a negative number is not a real number.
