The noise from a power mower was measured at 108 dB. The noise level at a rock concert was measured at 119 dB. Find the ratio of the intensity of the rock music to that of the power mower. (Round your answer to the nearest whole number.)

I tried by 108-119 =-11 but then I did 10^-11 and I got a weird answer so, I am having trouble trying ti figure this problem out step by step.

In the first place, you have your ratio backwards.

119-108 = 11 dB

So, the intensity is 10^1.1 = 12.6 times as much.
