Title: How to calculate log using a calculator
In the fields of mathematics and engineering, logarithm (log) is a common operation and is widely used in scientific computing, financial analysis and other fields. Many people may encounter the problem of how to calculate logarithms when using a calculator. This article will introduce in detail how to use a calculator to calculate logarithms, and provide hot topics and hot content in the past 10 days as a reference.
1. How to use a calculator to calculate logarithms
The logarithm calculation function of the calculator is usually divided into ordinary logarithms (logarithms with base 10) and natural logarithms (logarithms with base e). The following are the specific steps:
| Logarithmic type | Calculator keys | Example |
|---|---|---|
| Ordinary logarithm (log10) | log | Calculate log(100), directly enter 100 and press the log key, the result is 2 |
| Natural logarithm (ln) | ln | To calculate ln(10), directly enter 10 and press the ln key. The result is 2.302585 |
| Any base logarithm | Bottom changing formula | To calculate log2(8), use the base-changing formula: log(8)/log(2), the result is 3 |
