Hi I need help this problem I don't know how to start ... I'm completely lost thank you!

An amplifier increases the peak-to-peak voltage of a signal from 1 V to 20 V. What is the amplifier's gain in dB?

dB = 20 log10 (Vout/Vin)
Im guessing is that the formula that I have to use?

in this case dB = 20 log10 (20/1) ??
