1st step, DON'T PANIC. You have plenty of time to study. When it's a big exam, I like to set aside 2 hours daily for studying. If you're confused by certain topics, watch a video or ask your professor how to properly complete the answer. One college tip I learned: ALWAYS ASK THE PROFESSOR IF YOU GET CONFUSED WHILE STUDYING! They can help clear up problems you have. On the night before the exam, make sure you get a good night's rest. On the day of your exam, make sure to eat a good breakfast.

You have plenty of time, you got this! :)

The intensity, or loudness, of a sound can be measured in decibels (dB), according to the equation I(dB)=10log[1/10], where I &a

Alexandra [31]

For this case we have the following equation:
$I(dB)= 10log(\frac{I}{I0})$
Where,
I: the intensity of a given sound
I0: the threshold of a hearing intensity
Substituting values in the given equation we have:
 $I(dB)= 10log(\frac{10^8I0}{I0})$
Rewriting the equation we have:
 $I(dB)= 10log(10^8)$
Then, by properties of logarithm we have:
 $I(dB)= 10(8)$
Finally we have:
 $I(dB)=80$
Answer:
The intensity, in decibles, [I(dB)], when I=10^8(I0) is:
D.80
