Part 1 - Application The magnitude R (on the Richter scale) of an earthquake of Intensity I is defined as R = log7 1 .
Part 1 - Application The magnitude R (on the Richter scale) of an earthquake of Intensity I is defined as R = log7 1 . = minimum intensity used for comparison. Ms. Cohen felt an earthquake in Los Angeles that had an intensity of (5 x 10 ) (1 ). What was its magnitude, to one decimal place, on the Richter scale? Be sure to show and explain your work. Part 2 - Find the error(s) and solve the problem correctly. Solve. Be sure to show and explain your work. log , (x + 3) + log , (x - 3) = 2 Answer: log , (x + 3) + log , (x - 3) = 2 log (x + 3 + x - 3) = 2 log (2x) = 2 2 = 2x 16 = 2x 8 = x Part 3 - Discussion Question How do we know that e and In x are inverses of each other
