Hello there!
I’m not sure if they want me to add the answers together or just do them separately. 
Exponents
(-2)^2=(-2)(-2)=4
(7/6)^2=7/6(7/6)=49/36
I hope this helps!
Best wishes.

Answer:
7.34x10^22 kg can also be written as 0.0734 * 10^24 kg
Since both numbers are * 10^24, you can just add 5.97 + 0.0734 = 6.043. Then you have to add the * 10^24 giving you 6.043 * 10^24 kg
The ratio of Earth / moon is 5.97x10^24 / 7.34x10^22 = 81. The mass of the Earth is 81 times the mass of the moon.

The answer is -403
The order of operations puts multiplication before subtraction. -1 x 372= -372, and -372-31= -403
