1 answer:

3 0

Hello,
if express means simplify than
$\dfrac{x^2-2x+1}{x^2-4x+3y} \\

= \dfrac{(x-1)^2}{(x-2)^2-1} \\

= \dfrac{(x-1)^2}{(x-3)(x-1)} \\

= \dfrac{x-1}{x-3}$

Answer:

6045000000000000000000000 kg.

Step-by-step explanation:

We have been given that the mass of Earth is $5.972\times10^{24}$ kg. The mass of the Moon is $7.3\times10^{22}$ 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.

$5.972\times10^{24}=5972000000000000000000000$

$7.3\times10^{22}=73000000000000000000000$

$5.972\times10^{24}+7.3\times10^{22}$

$5972000000000000000000000+73000000000000000000000$

$6045000000000000000000000$

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