Work this problem involving scientific notation:

On a recent mission, the crew of the starship Intrepid, left Earth and traveled 349 000 000 000 000 000 km (d1) to take supplies to a colony on the third planet orbiting the star Arcturus. Their next stop was to check out a comet, which was 45 000 000 000 000 km (d2) away from Arcturus. After examining the comet, they traveled 427 000 000 000 000 000 km (d3) to return to earth. Convert these distances to scientific notation and calculate the total distance the crew traveled.


87.0x10^17 km

80.00X10^10 km

7.85X10^7 km

7.8X10^17 km

9.98X10^10 km

Answer 2

Answer:

$7.8\times 10^{17}$

Step-by-step explanation:

In scientific notation:

$d_1=3.49 \times 10^{17}$

$d_2=4.5\times 10^{13}$

$d_3=4.27 \times 10^{17}$

Write $d_2$ in the form of 10 raise to the power of 17 and then add the three distance to calculate the total distance travelled by the crew.

$d_1+d_2+d_3=(3.49+0.00045+4.27)\times 10^{17}=7.8\times 10^{17}$
