The mass of earth is 5.9 x 10^24. the mass of pluto is 13,000,000,000,000,000,000,000 kg. compared to pluto, how much greater is earth's mass?

5.9 × 10^24 = 5,900,000,000,000,000,000,000,000 minus
13,000,000,000,000,000,000,000 equals
5,887,000,000,000,000,000,000,000 kg
which is the amount greater that Earth's mass is. you could write this problem as
5.9 × 10^24 - 13 × 10^21 = 5.887 × 10^21
