@phi??
OpenStudy (lgbasallote):
\[87.907 \times 998\]
87.907 has 5 sig figs
998 has 3 sig figs
therefore, the product should have 3 sig figs
OpenStudy (lgbasallote):
and i wasn't even tagged.....
OpenStudy (anonymous):
so i would use scientific notation and turn \[87731.186 \implies 8.77\times10^4\]???
OpenStudy (anonymous):
you weren't tagged because you said you weren't good at it :\

OpenStudy (lgbasallote):
and you believed a level 99 who happens to be a troll
OpenStudy (anonymous):
dude, just do your thing and stop messing with my barely functioning brain -.-
OpenStudy (lgbasallote):
\[890,000 \times 830\]
both have 2 sig figs so product should be 2 sig figs
OpenStudy (lgbasallote):
\[73.2 \times 7000\]
73.2 has 3 sig figs
7000 has 1 sig fig
so product should have 1 sig fig
