What Is a Log & Exponent Calculator?

Logarithms and exponents are inverse operations. An exponent asks "what do you get when you multiply the base by itself repeatedly?" A logarithm asks the reverse: "what power do I need to raise the base to, to get this value?" This tool handles both directions for any base.

Exponential growth (bₓ)
Exponential curves grow the base by repeated multiplication; logs reverse that.

Formulas

Exponent: Result = BaseExponent
Logarithm: Result = log(Value) ÷ log(Base)

How to Use This Calculator

  1. Choose "Logarithm" or "Exponent" mode.
  2. Enter the base (e.g. 10 for common log, or any number for exponents).
  3. Enter the value (for logarithm) or the exponent (for exponent mode).
  4. Click "Calculate" to see the result.

Worked Example

Example: log base 2 of 1024: since 210 = 1024, the answer is 10. Exponent example: 210 = 1024.

What is the relationship between logs and exponents?

They're inverse operations — if b^x = y, then log base b of y equals x.

What's the difference between log and ln?

"log" typically means base-10; "ln" means natural log, base e.
