Use this when you know the base and result and want to find the exponent. - Solve Logarithmic (logₐ(b))
Use this when solving logarithmic expressions.
Step 2: Enter the Base (a)
Input the base number.
Examples:
- 2 (binary math)
- 10 (common logarithms)
- e (natural logs, approximated numerically)
Important: The base must be greater than 0 and not equal to 1.
Step 3: Enter the Value (b)
This is the result of the exponential equation or the argument of the logarithm.
Step 4: Click Calculate
Press the Calculate button. The tool shows a short progress animation and then displays the result.
Step 5: View the Results
You’ll see:
- Base value
- Input value

Understanding the Math Behind It (Simple Explanation)
Exponential Equations
An equation like aˣ = b asks:
“What power should we raise a to, to get b?”
Example:
3ˣ = 27 → x = 3
Logarithmic Equations
A logarithm is simply the inverse of exponentiation.
logₐ(b) = x means:
aˣ = b
Example:
log₂(8) = 3 because 2³ = 8
This calculator performs these inverse operations instantly.
