Many of us on the forum (I think including YOU) had this discussion a few months ago and decided this representation was rather ambiguous, but most agreed it is

[(8.4 x 10^7)/4] x 10^12     so your first solution is the one considered correct by most of us and most calculators too......     use brackets to be clear !!!
