Can someone help me? I'm really confused.

The loudness L of a sound in decibels is given by L= 10log(base10)R, where R is the sound's relative intensity. If the intensity of a certain sound is tripled, by how many decibels does the sound increase?

• Algebra 2 -

evaluate
L = 10log (3R)
= 10log3 + 10logR
= 4.77 + l0log R

so ....
