The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude R is given by the model below, where E is the energy (in kilowatt-hours) released by the earthquake.
R = 0.67 log (0.37E) + 1.46
Suppose an earthquake releases 14,500,000,000 kilowatt-hours of
energy. What is the earthquakeâ€™s magnitude? Round to three decimal places.
