College Algebra

This exercise deals with logarithmic scales.

Earthquake A had a magnitude of 8.2 on the Richter scale. At the same time an earthquake B with magnitude 4.8 caused only minor damage. How many times more intense was earthquake A than earthquake B? (Round your answer to two decimal places.)
I got 3.4 times to be the intensity of earthquake A, It was marked incorrect can anybody tell me what I did wrong.

  1. you were not quite done,
    3.4 is the difference in the Richter scale values,
    so the relative strength of the quakes is
    10^(3.4) = appr 2512 times as large

    remember that the Richter scale is a base 10 logarithm relationship
