The natural log or ln is the inverse of e. That means one can undo the other one i.e. ln (e x) = x. e ln x = x. To solve an equation with logarithm(s), it is important to know their properties. Several physical applications have logarithmic models. The magnitude of earthquakes, the intensity of sound, the acidity of a solution. Earthquakes. R = log I. The Richter scale is used to measure the intensity of an earthquake. The actual model is a little more complex, but it simplifies to the equation shown. where, we read ${\mathrm{log}}_{b}\left(x\right)$ as, “the logarithm with base b of x” or the “log base b of x.”; the logarithm y is the exponent to which b must be raised to get x.; Also, since the logarithmic and exponential functions switch the x and y values, the domain and range of the exponential function are interchanged for the logarithmic function.
