Question 50392: This looks quite not like anything I'm use to seeing and can't come up with the answer. Please help???
The decibel level of sound is given by D=10log(I/10^12), where I is the sound intensity measured in watts per square meter. Find the decibel level of a whisper at an intensity of 5.4 x 10^10 watts per square meter.

D=10log(I/10^12), where I is the sound intensity measured in watts per square meter. Find the decibel level of a whisper at an intensity of 5.4 x 10^10 watts per square meter.
----------
D=10log[5.4x 10^10/10^12]
D=10log[5.4 x 10^-2]
D=10log[0.054]
D=10(-1.2676...)
D=-12.676...
