If log M = x, then M is called the antilogarithm of x and is written as M = antilog x. For example, if log 39.2 = 1.5933, then antilog 1.5933 = 39.2.If the logarithmic value of a number be given then the number can be determined from the antilog-table. Antilog-table is similar to log-table; only difference is in the extreme left-hand column which ranges from .00 to .99. Example … [Read more...]

## Common Logarithm and Natural Logarithm

Here we will discuss about the common logarithm and natural logarithm. In Logarithm we have already seen and discussed that the logarithmic value of a positive number depends not only on the number but also on the base; a given positive number will have different logarithmic values for different bases. In practice, however, following two types of logarithms are used: (i) … [Read more...]

## Logarithm

In logarithm we will practice different types of questions on how to solve logarithmic functions on log. Solved examples on logarithm will help us to understand each and every log rules and their applications. Solving logarithmic equation are explained here in details so that student can understand where it is necessary to use logarithm properties like product rule, quotient … [Read more...]

## Logarithm Rules or Log Rules

In mathematics logarithm rules or log rules we have discussed mainly on logarithm laws along with their proof. If students understand the basic proof on general laws of logarithm then it will be easier to solve any types of questions on logarithm like ……… How to solve logarithm equations?There are four following math logarithm formulas: ● Product Rule Law:loga (MN) = loga M + … [Read more...]

## Convert Exponentials and Logarithms

In convert Exponentials and Logarithms we will mainly discuss how to change the logarithm expression to Exponential expression and conversely from Exponential expression to logarithm expression. To discus about convert Exponentials and Logarithms we need to first recall about logarithm and exponents. The logarithm of any number to a given base is the index of the power to … [Read more...]

## Mathematics Logarithms

In mathematics logarithms were developed for making complicated calculations simple. For example, if a right circular cylinder has radius r = 0.375 meters and height h = 0.2321 meters, then its volume is given by: V = A = πr2h = 3.146 × (0.375)2 × 0.2321. Use for logarithm tables makes such calculations quite easy. However, even calculators have functions like multiplication; … [Read more...]
