Power, Root & Log Calculator — Free Online Calculator

Calculates exponents, square/cube roots, and logarithms.

What is it?

The powers, roots, and logarithms calculator evaluates aⁿ, the n-th root ⁿ√a, a logarithm to any base, the natural log (ln), and the common log (lg).

Formula

Power: aⁿ n-th root: a^(1/n) log_b(a) = ln(a) / ln(b) ln(a) = log_e(a), lg(a) = log₁₀(a)

Example

2¹⁰ = 1024. ³√27 = 3. log₂(1024) = 10. ln(e) = 1. lg(100) = 2.
