Part 1 -Application The magnitude R (on the Richter scale) of an earthquake of Intensity l is defined as I O R=l0g I a =minimum intensity used for comparison. I Ms. Cohen felt an earthquake in Los Angeles that had an intensity of (5 x 10 6')(l a). 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. 2 log 4(x+3) +Iog 4(ac3) Answer: log 4(3: + 3) + log 4(x 3) II N 1094(x+3+x3) =2 log 4(2x) = 2 4 2: 23: 16:29: 823
