This log calculator (logarithm calculator) allows you to calculate the logarithm of a (positive real) number with a chosen base (positive, not equal to 1). Regardless of whether you are looking for a natural logarithm, log base 2, or log base 10, this tool will solve your problem. Read on to get a better understanding of the logarithm formula ...
log b (x / y) = log b x - log b y. EX: log (10 / 2) = log (10) - log (2) = 1 - 0.301 = 0.699. If there is an exponent in the argument of a logarithm, the exponent can be pulled out of the logarithm and multiplied. log b x y = y × log b x. EX: log (2 6) = 6 × log (2) = 1.806. It is also possible to change the base of the logarithm using the ...
The logarithm log b (x) = y is read as log base b of x is equals to y. Please note that the base of log number b must be greater than 0 and must not be equal to 1. And the number (x) which we are calculating log base of (b) must be a positive real number. For example log 2 of 8 is equal to 3.
An exponential equation is converted into a logarithmic equation and vice versa using b x = a ⇔ log b a = x. A common log is a logarithm with base 10, i.e., log 10 = log. A natural log is a logarithm with base e, i.e., log e = ln. Logarithms are used to do the most difficult calculations of multiplication and division.
In order to calculate log-1 (y) on the calculator, enter the base b (10 is the default value, enter e for e constant), enter the logarithm value y and press the = or calculate button: = Calculate × Reset
Free Logarithms Calculator - Simplify logarithmic expressions using algebraic rules step-by-step
However, they are all applicable for natural logarithms as well. Here are the most commonly used log formulas. log b 1 = 0; log b b = 1; log b (xy) = log b x + log b y; log b (x / y) = log b x - log b y; log b a x = x log b a; log b a = (log c a) / (log c b) Some of these rules have specific names like log b (xy) = log b x + log b y is called ...
The meaning of LOG is a usually bulky piece or length of a cut or fallen tree; especially : a length of a tree trunk ready for sawing and over six feet (1.8 meters) long.
The value of log base 10 can be calculated either using the common log function or the natural log function. Let’s calculate the value of log 10 using common logarithm., The value of log 10 10 is equal to the log function of 10 to the base 10. According to the definition of the logarithmic function, if log a b =x, then a x =b.
Log File. Files that use the .log file extension are commonly used by a variety of computer operating systems and software applications to store plain text or binary logs of events that have occurred within the associated software program. Log files are used for many different purposes. For example, they may be generated by operating systems to ...
Synonyms for LOG: record, report, transcribe, register, note, enter, mark, write down; Antonyms of LOG: miss, fail (at), lose, fall short (of)
What Is a LOG File? A file with the LOG file extension, sometimes called a logfile, is used by all kinds of software and operating systems to keep track of something that has occurred, usually complete with an event detail, date, and time. It could really be used for anything that the application deems appropriate to write down.

a, b, c are real numbers and b > 0, a > 0, a ≠ 1. a is called "base" of the logarithm. Example: 2 3 = 8 => log 2 8 = 3. the base is 2. Animated explanation of logarithms. There are standard notation of logarithms if the base is 10 or e . log 10 b is denoted by lg b. log e b is denoted by log b or ln b.
If you need a username and password (or other credentials) to access something, you are logging in. If you can access it without credentials (like this site), you are logging on. Here’s an easy way to remember log in vs. log on. Since the word credentials contains the letter I, like the word in, you can use this shared letter as a mnemonic ...
The notation is log b x or log b (x) where b is the base and x is the number for which the logarithm is to be found. There are several named logarithms: the common logarithm has a base of 10 (b = 10, log10), while the natural logarithm has a base of the number e (the Euler number, ~2.718), while the binary logarithm has a base of 2.
log on: [verb] to establish communication and initiate interaction with a computer or network.
A log may refer to any of the following: 1. Detailed list of an application information, system performance, or user activities. A log can be useful for keeping track of computer use, emergency recovery, and application improvement. Each software program that can create a log has different methods of starting or stopping the log creation.
