Answer:
780,000,000 km or 780 Gm
Explanation:
The approximate distance will be 5.2 times the length of an astronomical unit:
(5.2)(150,000,000) = 780,000,000 km
_____
SI standard prefixes are available for multipliers up to 10^18. Here, we have 7.8×10^11 m, so we can write that using standard prefixes as either of ...
780 gigameters = 780 Gm
0.78 terameters = 0.78 Tm
