So basically it's a question about astronamers measuring light-years
And well I need help because I'm stuck on this test and really just gotta turn it in to do my other work so if anyone can help please do so
Question: Astronamers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 x 10^12 miles. Suppose a star is 9.8 X 10^1 light-years from Earth. In scientific notation, approximately how many miles is it?
