In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. So the logarithm is 3. How to Write it. We write it like this: log2(8) = 3.
- Logarithm - WikipediaIn mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3.
- Logarithm Rules | ChiliMathRules or Laws of Logarithms. In this lesson, you’ll be presented with the common rules of logarithms, also known as the “log rules”. These seven (7) log rules are useful in expanding logarithms, condensing logarithms, and solving logarithmic equations.
- Logarithms | Brilliant Math & Science WikiA logarithm is the inverse of the exponential function. Specifically, a logarithm is the power to which a number (the base) must be raised to produce a given number. For example, \ (\log_2 64 = 6,\) because \ ( 2^6 = 64.\) In general, we have the following definition: \ ( z \) is the base-\ (x\) logarithm of \ (y\) if and only if \ ( x^z = y \).
- Intro to logarithms (video) | Logarithms | Khan AcademyJust Keith. 11 years ago. Logarithm is based on the combination of two Greek words: logos and arithmos (number). Logos (λόγος) is a rather curious Greek word with multiple meanings. In this case, you could translate it as "ratio" or "proportion". The word "logarithm" was invented by John Napier in 1614.
