ASAP! The Richter scale is used to measure the magnitude of an earthquake. The magnitude, R, is given by the equation r = 0.65log(0.39E)+1.45, where E is the energy (measured in kilowatt-hours) released by the earthquake. Determine the amount of energy released by an earthquake of magnitude 7.5. Simplify the problem so that is written in the form b = log a
