## Definition

describing a way of measuring things where the numbers grow very quickly. Instead of adding, each step on the scale multiplies the previous number.

For teachers: relating to or expressed in terms of logarithms, where a value represents the power to which a fixed base must be raised. Often describes scales used to measure phenomena with a vast range of intensities.

## Examples

- The Richter scale for earthquakes is logarithmic.
- Because the sound intensity varies so much, engineers use a logarithmic scale called decibels to measure it.
- In a logarithmic progression, equal distances on the axis represent equal ratios of change rather than equal increments of value, allowing for the visualization of exponential growth patterns.

## Usage notes

- Typically used in technical, mathematical, or scientific contexts; often precedes nouns like 'scale', 'growth', or 'function'.
