The var statement declares function-scoped or globally-scoped variables, optionally initializing each to a value. The name of the variable to declare. Each must be a legal JavaScript identifier or a destructuring binding pattern. Initial value of the variable. It can be any legal expression. Default value is undefined.

Log a/b + log b/a

In mathematics , many logarithmic identities exist. The following is a compilation of the notable of these, many of which are used for computational purposes. Trivial mathematical identities are relatively simple for an experienced mathematician , though not necessarily unimportant. Trivial logarithmic identities are:. Logarithms and exponentials with the same base cancel each other. This is true because logarithms and exponentials are inverse operations—much like the same way multiplication and division are inverse operations, and addition and subtraction are inverse operations. Logarithms can be used to make calculations easier. For example, two numbers can be multiplied just by using a logarithm table and adding. These are often known as logarithmic properties, which are documented in the table below. The laws result from canceling exponentials and the appropriate law of indices. Starting with the first law:. This can be done more easily by rewriting in terms of exponentials, whose properties we already know.

Log rules refer to the rules of logarithms. These rules are derived from the rules of exponents as a logarithm is just the other way of writing an exponent. The logarithm rules are used:. Let us learn more about log rules and we will solve some example problems using the logarithm rules. Log rules are rules that are used to operate logarithms. Since logarithm is just the other way of writing an exponent, we use the rules of exponents to derive the logarithm rules. There are mainly 4 important log rules which are stated as follows:. Along with these rules, we have several other rules of logarithms.

Log a/b + log b/a

The properties of log are used to expand a single logarithm into multiple logarithms or compress multiple logarithms into a single logarithm. A logarithm is just another way of writing exponents. Thus, the properties of logarithms are derived from the properties of exponents. Let us learn the properties of log along with their proofs and let us solve a few examples also using these properties. The properties of log are nothing but the rules of logarithms and these are derived from the exponent rules.
