Question

Saturn is 8.7 x 108 miles from the sun. The earth is 9.1 x 10' miles from the sun. How much closer to the sun is one planet than the other?

Answer 1

Saturn is:

`8.7*10^8`

and earth is:

`9.1*10^7`

so we can made the cienthific notation equal so:

`8.7*10^8=87*10^7`

so now we can rest the difference so:

`\begin{gathered} 87*10^7-9.1*10^7 \\ =77.9*10^7 \end{gathered}`
