Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approxi
mately 5.88 x 1012 miles. Suppose a star is 1.23 x 102 light-years from Earth. In scientific notation, approximately how many miles is it? 12.3 x 10^12
7.23 x 10^13
7.23 x 10^14
5.88 x 10^12
When you divide one number by another, the result is called the quotient. This is true for rational expressions too! When you divide one rational expression by another, the result is called the quotient.
