A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. Because logarithms relate geometric... In other words, The logarithm of a number y with respect to a base b is the exponent to which we have to raise b to obtain y. We can write this definition as x = log b y ---> b x = y and we say that x is the logarithm of y with base b if and only if b to the power x equals y. Let's illustrate this definition with a few examples. If you have difficulties with any of these powers go back to my

Let's take logarithms of both sides of the equation as in panel 9. You can see that, if y = ax b , then a graph of log y vs log x yields a straight line of slope b and y intercept log a. Conversely, if a graph of log y vs log x for a set of data is a straight line, then the data does indeed follow the relation y = ax b .

Calculating Logarithms Sciencing
Logarithms are the inverse of the exponential function. Originally developed as a way to convert multiplication and division problems to addition and subtraction problems before the invention of calculators, logarithms are now used to solve exponential … games to teach kids how to count money 2005-02-28 · Logarithms reduced the needed amount of work by a large amount, way more than half I'd guess. Now that calculators and computers are common, logarithms are still very, very useful, but in a totally different way. They are very closely related to exponential functions. For example, you probably know by now that y = a^x is equivalent to log_a(y) = x, where log_a(y) is the base a logarithm of y. How to tell if sugar is mixed with baking soda
