Greenberg's logarithmic model

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.
