Question 551601
The Peru quake released 1.74*10(5+1.44*8.1) = 1.74*10^16.664<P>
The Mexico quake released 1.74*10^(5+1.44*7.6) = 1.75 * 10 15.944<P>
To find how many more times one number is than another, divide the numbers.  For example if the numbers are 4 and 6, then 6 is 6/4 = 1.5 times 4.<P>
Remember that when dividing the same number to different powers, subtract the powers.<P>
1.74*10^16.664 / 1.74 * 10^15.944 = 10^(16.664-15.944) = 10^.67 = approximately 4.68 times more energy released by the Peru quake.
