The intensity I of an earthquake is measured by a seismograph-a device that measures amplitudes of shock waves. lo is a minimum reference intensity of a "zero-level" earthquake against which the intensities of other earthquakes may be compared. The magnitude M of an earthquake of intensity / is given by log Io M Find the magnitude of an earthquake whose intensity is 56,987 times Io Round your answer to 3 decimal places.

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
