Question

Find the magnitude R of an earthquake with a relative size s = 5,641,200. (R = log s)Round to the nearest tenth.

Answer 1

R = 6.8

Step-by-step explanation

If the magnitude R of an earthquake is given by the equation,

`R=\log s`

And, in this problem, s = 5,641,200, then the magnitude is,

`R=\log(5,641,200)\approx6.8`

Hence, the magnitude of this earthquake is 6.8, rounded to the nearest tenth.
