The mass of Earth is 5.97x10^24 kilograms. The mass of the moon is 7.34x10^22 kilograms.
Part A:
What is the combined mass of Earth and the Moon ? Express your in scientific notation.

Part B:

How many times as great is the mass of the Moon ? Express your answer in scientific notation.

Answer 1

5.97 x 10^24 + 7.34 x 10^22
= 5.97 x 10^24 + .0734 x 10^24
= 6.0434 x 10^24

5.97 x 10^24 / 7.34 x 10^22
= (5.97/7.34) x 10^2
= .8133 x 10^2
= 8.133 x 10^1
