Thus, the logarithm of a number is the exponent to which the base has to be raised to reach that number. Many times an arithmetic calculation can be done in a simpler way by appealing to the logarithms. The logarithms can be calculated very simply from the following: ...
This post is a sequel to the postHow Mr. Bidder calculated logarithmspublished a few days ago. As with that post, this post is based on an excerpt fromThe Great Mental Calculatorsby Steven B. Smith. Smith’s book saysArthur Benjaminsquares large numbers using the formula n² = (n+a)(...
Common logarithms is of base 10 which is calculated using the logarithm tables. Q2 How find the logarithm of a given number? Using the logarithm table, Calculate the characteristic, which is determined by the whole number part of the given number. ...
When a value is missing (typically only for books, conference proceedings or reputation data), a substitute value of 0 is used instead. For the 10 indicators that use logarithms, as it is not possible to calculate the log of 0, a substitute value of -0.5 is used wherever this occurs. ...

The following rules are essential to learn if you want to solve various equations involving natural logarithms effectively.Product rule log10(x*y) = log10(x) + log10(y) The log10 of the multiplication of x and y is the sum of the log10 x and log10 y. Example, log10(5*10) = ...
Exponentials and Logarithms The exponential function exhas the property that its derivative is equal to the function itself. Therefore: d/dx ex= ex Finding the derivative of other powers of e can than be done by using the chain rule. For example e2x^2is a function of the form f(g(x)...
But not only did he prove that he was a highly proficient calculator – he reputedly memorized the values of 14,000 logarithms – Oppolzer also made astronomical observations directly from his own private observatory in Vienna-Josephstadt. Equipped with a revolving dome, a 7-inch refracting tele...
