Solve.Suppose that we want to measure the magnitude of an earthquake. If an earthquake has a shock wave x times greater than the smallest shock wave that can be measured by a seismograph, then its magnitude R on the Richter scale is given by the equation R = log x. What is the magnitude of an earthquake that has a shock wave that is 123,000times greater than the smallest shock wave that can be detected? If necessary, round to two decimal places.
A. 5.09
B. 0.09
C. 0.2
