Root Calculator
The n-th root of a value.
How it works
Result = value^(1/n)
n = 2 is the square root, n = 3 the cube root. Negative values only have odd-degree real roots.
Worked example
√144 = 12; ∛27 = 3; √2 ≈ 1.414.
Fractional exponents are equivalent: 8^(1/3) = ∛8 = 2.
Notes and limitations
Even roots of negative numbers are not real; odd roots are fine. Roots and powers are inverses, but √(a+b) ≠ √a + √b — one of the most common algebra mistakes.
