Question

The moon has a mass of 7.35x1022, while earth has a mass of 5.97x1024 Kg. What is the combined mass of the moon and earth.

Answer 1

6.0435*10²⁴

Explanation:

Moon: 7.35*10²²

Earth: 5.97*10²⁴

7.35*10²² = 0.0735*10²⁴

then:

0.0735*10²⁴ + 5.97*10²⁴ = (0.0735 + 5.97)*10²⁴

= 6.0435 *10²⁴
