## Log problem

I have

Its a problem about sound levels where I = 10^-12 W/m^2 and L is counted in decibels (db)

The problem, what is x if L = 65 db

I know i should take the log of 65 somehow and i think * it by the log of I, but am not really sure

also in the picture the I has a lowewed 0 on it but i dont know how to right that or even what that means i have only seen raised ^
