Understanding Logarithm Base 10
The logarithm base 10, also known as the common logarithm, is the logarithm to the base 10. It is written as log10(x), log(x), or sometimes simply log x when the base 10 is implied.
Definition: The base 10 logarithm of a number y is the exponent to which 10 must be raised to produce y. In other words, if x = log10(y), then 10x = y.
Formula: log10(y) = x is equivalent to 10x = y.
Use Cases:
- Measuring Earthquake Intensity (Richter Scale): Uses base 10 logarithms to quantify the magnitude of earthquakes.
- Sound Intensity (Decibels): Measures sound levels on a logarithmic scale, making it easier to represent a wide range of sound intensities.
- Chemistry (pH Scale): The pH scale is logarithmic and is used to measure the acidity or basicity of a solution.
- Astronomy: Used in the magnitude scale to measure the brightness of stars and other celestial objects.
Example: log10(100) = 2, because 102 = 100. Similarly, log10(1000) = 3, because 103 = 1000.
