Answer 1

Answer:

distance . 4.3 light-years

= 4.3 × 1 light-year

= 4.3 × (5.88 × 10 miles)

12

= (4.3 × 5.88) × 10 miles

12

= (25.284) × 10 miles 7 NOT scientific notation (25 > 10) 12

= (2.5284 × 10 ) × 10 miles convert 25.284 to scientific notation 1 12

= 2.5284 × (10 × 10 ) miles

1 12

= 2.5284 × (10 ) miles

1+12

= 2.5284 × 10 miles

13

Answer: about 2.5284 × 10 miles
