Answer 2

Hey mate

Mass of the earth =(5.97*10 to the power 24 )kg

= (597.00*10 to the power 22)kg.

Mass of the moon=(7.35*10 to the power 22)kg.

Total mass of the two=(597*10 to the power 22) kg+(7.35*10 to the power 22) kg.

=(597+7.35)10 to the power.

22kg.

=604.35*10 to the power

220 kg.
