## Why is log used in math?

Logarithms are a convenient way to express large numbers.

(The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division.

(This benefit is slightly less important today.).

## What is a log list?

On a Web server, an access log lists all the individual files that people have requested from a website. These files will include the HTML files and their imbedded graphic images and any other associated files that get transmitted.

## What is the formula of log a log B?

This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. The same base, in this case 10, is used throughout the calculation. You should verify this by evaluating both sides separately on your calculator.

## How does a log work?

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

## What log means?

1 : a large piece of a cut or fallen tree. 2 : a long piece of a tree trunk ready for sawing. 3 : the record of a ship’s voyage or of an aircraft’s flight the captain’s log. 4 : a record of performance, events, or daily activities a computer log.

## Why is it called a log?

Q: Why are logs called logs? A: The name refers to the fact that they are like entries in ship’s logbook.

## How do you write 1 as a log?

The logarithm of x=1 is the number y we should raise the base b to get 1. Then the base 10 logarithm of 1 is 0.

## How do you find the log and antilog?

So converting from natural logs to common logs is sort of like changing units. Divide a natural logarithm by 2.303 to compute the common log of the same value. Multiply a common log by 2.303 to obtain the corresponding natural log. The antilogarithm (also called an antilog) is the inverse of the logarithm transform.

## What is log file in Mobile?

In Android, logs are a shared resource and are available to an application with the READ_LOGS permission. Even though the phone log data is temporary and erased on reboot, inappropriate logging of user information could inadvertently leak user data to other applications.”

## What are the log rules?

Basic rules for logarithmsRule or special caseFormulaProductln(xy)=ln(x)+ln(y)Quotientln(x/y)=ln(x)−ln(y)Log of powerln(xy)=yln(x)Log of eln(e)=12 more rows

## What is the log of 0?

log 0 is undefined. It’s not a real number, because you can never get zero by raising anything to the power of anything else.
