The decibel level for the intensity of a sound is a logarithmic scale dened by D = lOloglo (I) + 120, where I is the intensitj of the sound in watts per square meter. Express I as a function of D. (Express numbers in exact form. Use symbolic notation and fractions where needed.) 1(1)) = \ When 1) increases by 23, the intensity increases by what factor? (Use decimal notation. Give your answer to one decimal place.) intensity increases by
