 Suppose that a*=n, then x is called the logarithm of n to the base a : thus the logarithm of a number to a given base is the index of the power to which the base must be raised to be equal to the number. The logarithm of n to the base a is written log.  Elementary Trigonometry - Page 84by James Hamblin Smith - 1870 - 224 pagesFull view - About this book
