## anonymous 4 years ago word problem involving logarithms. I will type it as an equation, please help!

1. anonymous

The level of sound V in decibels with an intensity I can be modeled by

2. anonymous

$V=10 \log (I/10^(-16))$

3. anonymous

where I is intensity in watts per centimeter. Loud music can have an intensity of 10^(-5) watts per centimeter. Find the level of sound of loud music.

4. lalaly

$V=10\log \frac{10^{-5}}{10^{-16}}$

5. anonymous

So far i have V=10 log (10^(-5)/10^(-16))

$=10\log 10^{11}$

8. lalaly

$=10 \times 11 =110$
