Eh not really sure bout this one
Answer: the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
Explanation: Given that sound at a rock concert power is 130 dB of intensity l2
a whisper power is 2 dB of intensity l1
Using the formula
130dB - 2dB = 10Log(I2/I1)
128/10 = logI2/I1
12.8 = log (I2/I1)
I2/I1 = 6.31 × 10^12
Therefore, the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
