( timed)the intensity, or loudness, of a sound can be measured in decibels (db), according to the equation i(db)=10log[1/10], where i & / the intensity of a given sound and i0 is the threshold of a hearing intensity. what is the intensity, in decibles, [i(db)], when i=10^8(i0)? round to the nearest whole number. (refer to photo for equations) a.8 b.9 c.19 d.80

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
