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.
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.
Logarithms. This booklet explains what is meant by a logarithm. It states and illustrates the laws of llogarithms. It explains the standard bases 10 and e. Finally it shows how logarithms can be used to solve certain types of equations.
27 Μαρ 2023 · A logarithm is simply the number of times we need to multiply one number together to make another number i.e. it is the power to which a number must be raised to get another number. Logarithms allow us to deal with extremely large or extremely small numbers without getting our heads in a spin.
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.

6 Οκτ 2021 · The logarithm base \(e\) is called the natural logarithm and is denoted \(\ln\:x\). Logarithmic functions with definitions of the form \(f (x) = \log_{b}x\) have a domain consisting of positive real numbers \((0, ∞)\) and a range consisting of all real numbers \((−∞, ∞)\).
