In mathematics, logarithmic rules represent different ways of writing exponents. Log rules are used to compact a set of logarithms into a single-digit logarithm. On the other way, log rules have the power to expand only logarithms into a vast range of logarithms. Logarithms are speedily adopted by scientists as it has useful components that help in simplifying complex calculations.

Particularly, in log rules two numbers that are m and n seek logarithms for each number in a particular table. After adding log rules, review the tables to find numbers with intended logarithms.

What are Logarithmic Rules?

Logarithmic rules are used to operate exponents in different ways. The logarithms provide accurate answers when a single digit is multiplied several times. (Eg: if 2 multiplied 3 times, 8 will be the answer. So, the base 2 logarithms 8 is 2). There are four primary rules to derive exponent from log rules.

Product rule- logb mn = logb m + logb n
Quotient rule- logb m/n = logb m - logb n
Power rule- logb mn = n logb m
Change of base rule- loga b = (log b) / (logc a)

Different Types of Logarithms

There are two types of logarithms commonly used in mathematics, common logarithm and natural logarithm.

1. Common logarithm: The base 10 logarithms, also known as simply log, show result 1000. It needs to be calculated how many times multiply the digit to get the result 1000. (Eg. Log (10) =10 is 1000, 10 multiply 10 times to get 1000)

2. Natural logarithm: The natural logarithm represents the mathematical constant e, which is equivalent to 2.718281828459. It is mainly used in mathematical applications. Moreover, physical and biological sciences use natural logarithm rules to analyze appropriately. (Eg. In (78) = 4.357, the base e logarithm of 78 is equivalent to 4.357)

Various Application of Logarithm Rules

Logarithm rules are predominantly used in different areas of science and technology.

Scientists and analysts are largely embracing logarithm calculators for easier calculation.

Nowadays applications are widely used to measure decibels in noise pollution, and radioactivity and identify chemical components.

Log rule-based applications are commonly used in celestial navigation and surveys.

Logarithm application is used in the Richter scale to measure an earthquake's intensity.

In supporting of the above topic logarithm rules have importance in everyday life. The log rules are derived from the logarithm to get appropriate results using easier calculations. In mathematics, log rules define coordination between two different variables. Then the generated values are portrayed as functions of the logarithm rules.
