The mass of Earth is 5.97 X 10²⁴ kilograms. The mass of the Moon is 7.34 x 10²² kilograms. What is the combined mass of earth.
Damm [24]

Answer:

13.31 x 10^{46}

Step-by-step explanation:

So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31

Then if we add the two tens together it would be: 10^2^2 + 10^{24 = 10 to the power of 46.

The equation would be 13.31 x 10^{46}

I'm not an expert, so sorry if this is wrong.
