Answer:
Option B - [tex]=8.4672\times 10^{13}[/tex]
Step-by-step explanation:
Given : Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5,880,000,000,000 miles.Suppose a star is 14.4 light years from earth.
To find : In scientific notation, how many miles away a star is from earth?
Solution :
One light-year is the distance that light can travel in one year is = 5,880,000,000,000 miles.
In scientific notation, [tex]5.88\times 10^{12}[/tex] miles.
In 14.4 lights year the distance is [tex]=14.4\times5.88\times 10^{12}[/tex]
In 14.4 lights year the distance is [tex]=84.672\times 10^{12}[/tex]
or [tex]=8.4672\times 10^{13}[/tex]
Therefore, Option B is correct.
