In mathematics the logarithm is the inverse function to exponentiationThat means the logarithm of a given number x is the exponent to which another fixed number the base b must be raised to produce that number xIn the simplest case the logarithm counts the number of occurrences of the same factor in repeated multiplication. Trigonometry of the triangle. First lets find some log values and see what they mean when re-expressed in index notation.
Therefore log 00046 log 46 log 0001 066276 3 233724.
In the example of a number with a negative exponent such as 00046 one would look up log 46 066276. Therefore log 00046 log 46 log 0001 066276 3 233724. The logarithm is denoted in bold face. How to do easy calculation using log book.
