Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 *10^12 miles. Suppose a star is 3.2 * 10^2 light-years from Earth. In scientific notation, approximately how many miles is it?

1.88 * 10^12
5.88 * 10^14****
3.2 * 10^15
1.88 x 10^15
Please tell me if I am right. Thanks

no, look below carefully

3.2*10^2 LY ( 5.88*10^12 mi/LY)

= 18.8 * 10^14 mi

= 1.88 * 10^15 mi
