Logarithmus-Rechner

How to use it

1. Value x = 256, base b = 4
2. Apply change of base formula: ln(256) ÷ ln(4)
3. Berechnette: 5.5452 ÷ 1.3863
4. Result: logâ‚„(256) = 4 (since 4⁴ = 256)

Common mistakes

• ⚠️ Trying to calculate log of negative number or zero
• ⚠️ Using base = 1 which is undefined
• ⚠️ Confusing natural log with log base 10

Worked example

Berechnette the logarithm of 256 with base 4

The logarithm {log_val} is the power to which the base must be raised to get x
