A light year is the distance that a light travels through a vacuum (space without matter) in one year. A light year is about 9.46 x 10^12km. The distance to the spiral galaxy NGC 4603 is about 1.08 x 10^8 light years. What is the distance in km?
Online "*" is used to indicate multiplication rather than "x", which is often used to indicate an unknown.
(1.08 * 10^8)(9.46 * 10^12) = ?
