...[Above examples from Mechanical Engineer's Pocket Book. Wm. Kent.] LOGARITHMS The logarithm (log.) of a number is the exponent of the power to which it is necessary to raise a fixed number or base to produce the given number. Thus if the base is 10, the log. of 100 is 2, for 102 = 100. Logarithms...
