In the first case it is probably sufficient to ensure that the preceeding character was a digit and that the following character is a non-word character so s/(?<=\d)mp\b//g should do that one.

In the second case it is actually even simpler, no zero width look back assertion required: s/\s+\d+x Zoom//g.

Update: fixed broken regex. Was s/(><=\d)mp\b//g
