The first, and perhaps the most important step, in understanding logarithms is to realize that they always relate back to exponential equations.
1 Νοε 2013 · Logarithms are the inverse functions of exponential functions. The logarithm of a number b with base a, written as loga(b), represents the power to which a must be raised to equal b. For example, if log2(8) = 3, then 23 = 8. Logarithm functions are increasing and have asymptotes along the y-axis, with loga1 = 0 and logaa = 1. Read less
6 Μαρ 2012 · The document provides examples of converting between exponential and logarithmic forms using different bases, and notes that the base and output must be positive numbers. 1. The Logarithmic Functions. 2. There are three numbers in an exponential notation. The Logarithmic Functions 4 3 = 64. 3. There are three numbers in an exponential notation.
13 Ιαν 2012 · John Napier, a Scottish mathematician and astronomer, discovered logarithms in the late 16th century as a way to simplify calculations. He introduced the concept of logarithms to ease complex mathematical computations.
Logarithmic Functions. Suppose b ! 0 and b z 1. Then log b x 1 log b x 2 if and only if x 1 x 2 Basically, with logarithmic functions, if the bases match on both sides of the equal sign , then simply set the arguments equal.
10 Σεπ 2014 · Logarithms. Properties and Uses. Some background. A logarithm (generally called the “log” of a number) is the “power to which a given base must be raised to equal that number.” Common bases: Base 10 and Base e. Examples. Base 10 logarithms: 10 * 10 = 100. So 10 squared equals 100. 215 views • 19 slides
