The Richter scale converts seismographic readings into numbers for measuring the magnitude of an earthquake according to this function M(x) = log 
, where xo = 10-3.Find the magnitude (to one decimal place) of an earthquake whose seismographic reading is 2000 millimeters at a distance of 100 kilometers from its epicenter.
What will be an ideal response?
The magnitude of the earthquake measures 6.3 on the Richter scale.
