Final answer:
The average distance from Jupiter to the Sun in standard form is 778,400,000 km, aligning with option C after moving the decimal point eight places to the right.
Correct option is C 778,400,000 km
Step-by-step explanation:
The average distance from Jupiter to the Sun is given as 7.784 x 10⁸ km. To write this distance in standard form, you need to shift the decimal point eight places to the right, because the exponent on the 10 indicates the number of places to move the decimal.
Starting with 7.784, moving the decimal point eight places to the right gives us 778,400,000 km. Therefore, the correct way to write this distance in standard form is 778,400,000 km, which matches option C.
