On the Richter scale, the magnitude R of an earthquake is given by the formula 
where I is the intensity of the earthquake being measured and I0 is the standard reference intensity.
?
What is the magnitude of an earthquake that has intensity 10 millions times that of I0?
?
R = __________
?
Suppose an earthquake is measured with a magnitude of 5 on the Richter scale with an error of at most 2%. Use differentials to find the error in the intensity of the earthquake.
?
Hint: Observe that 
and use logarithmic differentiation. Round your answer to the nearest integer.
