Weblogb(x) = log(x) log(b) or. logb(x) = ln(x) ln(b) We use log or ln simply because calculators have LOG and LN buttons. In theory, any other logarithm loga could be used: logb(x) = loga(x) loga(b) which is called the generic change of base formula. It allows us to convert from one base to any other base. QUICK CHECK. WebThe easier one to explain is the ease of computation / comparation. The logarithmic system I think that's simple to explain is the pH model, which most people are at least vaguely aware, you see, the p in pH is actually a mathematical code for "minus log of", so pH is actually #-log[H]#.
