Add the first four planets:
5.79* 10^7 + 6.72*10^7 + 9.3*10^7 + 1.416*10^8
Add the first two together first:
5.79* 10^7 + 6.72*10^7 = 12.51*10^7
Rewrite it in proper scientific notation: 1.251*10^8
Now add that to the other planet with 8 as an exponent:
1.251*10^8 + 1.416*10^8 = 2.667*10^8
Now you have 2.667*10^8 + 9.3*10^7
Factor 10^7 out of each term:
10^7(2.667 *10) + 10^7 * 9.3
Factor 10^7 out of the equation:
10^7(2.667 *10 + 9.3)
Simplify to get 35.97*10^7
Rewrite in proper scientific notation:
3.597*10^8
Now both this answer ans Jupiter's distance have 10^8 so you need to compare the integers:
3.597 is less than 4.836, so Jupiter's distance is more than the combined distances of the other four planets.
