Acoustics In Exercises \(76-78\) , the loudness measured in decibels \((d B)\) is defined by loudness \(=10\) log \(\frac{I}{I_{0}},\) where \(I\) is the intensity and \(I_{0}=10^{-12} \mathrm{W} / \mathrm{m}^{2}\) . A screaming child can reach 90 dB. A launch of the space shuttle produces sound of 180 \(\mathrm{dB}\) at the launch pad. a. Find the intensity of each sound. b. How many times as intense as the noise from a screaming child is the noise from a shuttle launch?
Solve each equation. If necessary, round to the nearest ten-thousandth. $$ \log _{8}(2 x-1)=\frac{1}{3} $$
Solve each equation. Check your answers. $$ 3 \log x=1.5 $$
