Logarithms are the mathematical function that is used to represent the number (y) to which a base integer (a) is raised in order to get the number x: x = ay; where y = loga(x). Most of you are familiar with the standard base-10 logarithm: y = log10(x); where x = 10y.

19 Ιουλ 2024 · Definition: The common logarithm of a number is the power to which the number 10 must be raised to obtain that number. Usage : Widely used in scientific calculations, such as measuring the intensity of earthquakes (Richter Scale) and sound (decibels).
After reading this text and / or viewing the video tutorial on this topic you should be able to: explain what is meant by a logarithm. state and use the laws of logarithms. solve simple equations requiring the use of logarithms.
13 Φεβ 2023 · A common question exists regarding the use of logarithm base 10 (\(\log\) or \(\log_{10}\)) vs. logarithm base \(e\) (\(\ln\)). The logarithm base \(e\) is called the natural logarithm since it arises from the integral:
Logarithms and Exponentials. The common logarithm of a number (log) is the power to which 10 must be raised to equal that number. For example, the common logarithm of 100 is 2, because 10 must be raised to the second power to equal 100. Additional examples follow.
30 Απρ 2009 · Most will have encountered the term pH, but a chemist should be familiar with its formal definition, ie: pH = -log 10 ([H + ]/mol dm -3 ) The definition is written to emphasise an important point, ie one can only take the logarithm of a dimensionless quantity, which in most cases is one without units.
