Answer:
Option B - \(=8.4672\times 10^{13}\)
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, \(5.88\times 10^{12}\) miles.
In 14.4 lights year the distance is \(=14.4\times5.88\times 10^{12}\)
In 14.4 lights year the distance is \(=84.672\times 10^{12}\)
or \(=8.4672\times 10^{13}\)
Therefore, Option B is correct.
