The Richter scale measures earthquake intensity using the formula \(M = \log_{10} \left(\frac{I}{I_0}\right)\), where \(M\) is the magnitude, \(I\) is the intensity of the earthquake, and \(I_0\) is the intensity of a standard earthquake.
An earthquake has a magnitude of \(4.5\) on the Richter scale. Find the intensity ratio \(\frac{I}{I_0}\) (give your answer in scientific notation with 3 significant digits).
