ately 5,880,000,000,000 miles. Suppose a star is 14.4 light-years from Earth. In scientific notation, how many miles away is it 5.88 x 1013 miles 1.44 x 1012 miles 5.88 x 1012 miles 8.4672 x 1013 miles
This is one of those problems where you don't actually have to know anything. The only answer that is any combination of the two given numbers is the last one: .. 8.4672*10¹³ miles
_____ That result is the product of 5.88*10¹² and 14.4.
