(I'm going to use brackets as my absolute value bars lol)
[5 x -3]
[-15]
=15
1 step (B): raise both sides of the equation to the power of 2.
.
2 step (A): simplify to obtain the final radical term on one side of the equation.
.
3 step (F): raise both sides of the equation to the power of 2 again.
.
4 step (E): simplify to get a quadratic equation.
.
5 step (D): use the quadratic formula to find the values of x.
.
6 step (C): apply the zero product rule.
.
Additional 7 step: check these solutions, substituting into the initial equation.
Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is
kg. The mass of the Moon is
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.



Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
