Please check this logarithm question...
The loudness level of sound can be expressed by comparing the sound's intensity to the intensity of a sound barely audible tot he human ear. The formula D = 10(log I  log I0) describes the loudness level of a sound. D, in decibels, where I is the intensity of the sound, in watts per meter^2, and I(0) is the intensity of a sound barely audible to the human ear.
a. Express the formula so that the expression in parentheses is written as a single logarithm.
b. Continued below...

Best ResponseYou've already chosen the best response.0this is what i have D = 10log(100Io/Io) D = 10log(100) D = 10*2 D = 20
