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.
PowerPoint Presentation. Introduction To Logarithms. Logarithms were originally developed to simplify complex arithmetic calculations. They were designed to transform multiplicative processes into additive ones. If at first this seems like no big deal, then try multiplying 2,234,459,912 and 3,456,234,459. Without a calculator !
6 Μαρ 2012 · The document discusses logarithmic functions and how they relate to exponential forms. It explains that logarithmic functions take the form logb (y)=x, where b is the base, y is the output, and x is the exponent. This is equivalent to the exponential form bx=y.
13 Ιαν 2012 · Logarithms. 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.
1 Introduction to Logarithms. Lesson 7.4A Introduction to Logarithms. 2 Solve 20 = 10x How can this be done? Can you estimate the answer to the nearest whole number? Can you use trial and error (with a calculator) to find the answer to the nearest tenth? There must be an easier way! 3 Logarithms are the inverses of exponents. They can “undo” them.
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
