The number of decibels, d, produced by an audio source can be modeled by the equation d = 10 log(5)

where I is the sound intensity of the audio source and

K is a constant. How many decibels are produced by an

audio source whose sound intensity is 1,000 times the

value of K?

K. 10.000

Idon’t know the answer to this

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
