Question 1153142: About how many times more intense is an earthquake that measures 8.1 on the Richter scale than an earthquake that measures 7.4 on the Richter scale? Recall that Richter defined the magnitude R of an earthquake of intensity I to be
R = log I.
(Round your answer to two decimal places.)

log%28+I%29=8.1+-7.4
log%28+I%29=0.7
I=antilog%280.7%29
I=5.01
an earthquake that measures 8.1 is +5.01 times more intense
