The intensity of sound is measured in decibels (dB) using the formula \(L = 10 \log_{10} \left(\frac{I}{I_0}\right)\), where \(L\) is the sound level in decibels, \(I\) is the intensity of the sound, and \(I_0\) is the reference intensity (threshold of human hearing).
A sound has a level of \(75\) decibels. Find the intensity ratio \(\frac{I}{I_0}\) (give your answer in scientific notation with 3 significant digits).
