Use the formula;L=10*logI/I_0.In Albuquerque, New Mexico, the maximum allowable sound level from a car's exhaust is 96db.What is the intensity of such a sound?
My answer: 96=10*logI/10^-12
9.6=logI-log10^-12
9.6=logI-(-12_
-2.4=logI
10^-2.4=I
I s this correct?

Your result looks correct, but your typing is not very good. (You need to type grouping symbols, to indicate the proper Order of Operations.)

Also, I would declare the units, when reporting the intensity.
