Exponential and Logarithmic Equations · Exercise 71

Solve for the indicated value, and graph the situation showing the solution point.

The formula for measuring sound intensity in decibels $D$ is defined by the equation $D=10log\left(\frac{I}{I_0}\right),$ where $I$ is the intensity of the sound in watts per square meter and $I_0=10^{-12}$ is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of $8.3\cdot 10^2$ watts per square meter?

Its source prints no answer for this problem, so there's nothing to check against.
