100mm x 3 = 300mm
So while both lens are 3X, they both are drastically different on how far they can "zoom".
So yeah, the "X" means nothing more than the factor you multiply the wide end to get the telephoto end of the zoom.

Boy, you opened up a rookie's understanding. Now I want to start shooting with this old Minolta ST-T202. I got a Macro 1:2.8 MD f=28mm and a Rokkor 1:17 f=50mm MC !
(who needs digital zoom?)
