Will there ever be an instance where the natural log of the volumes not be needed? I noticed some notations for irreversible work of expansion as w= -nRT(V2/V1) without the ln, is it just implied?

Well, usually for irreverisible, work = -Pex * (delta V). I am not sure where your equation came from. I believe in this class for reversible, isothermal expansion, all you have to worry about is the one with natural log.
