Answer 1

Mercury is the closest planet to the Sun at a distance of 36 million miles is the closest star to the sun is Proxima Centauri which is 4.24 light years away light year is 5.9 * 10^12 miles

Part A

we have that

36 million miles is equal to

`36,000,000=36\cdot10^6\text{ miles=3.6}\cdot10^7\text{ miles}`

Part B

step 1

Multiply 4.24 light years by 5.9 * 10^12 miles

`4.24\cdot5.9\cdot10^((12))=25.016\cdot10^((12))\text{ miles=2.5}\cdot10^((13))\text{ miles}`

Part C

Divide both numbers

so

`\frac{\text{2.5}\cdot10^((13))}{\text{3.6}\cdot10^7}=0.7\cdot10^6`
