You have to see which onw is bigger
4^1 * 4^2 = 4^(1 + 2) = 4^3 = 64
5^3 * 5^-6 = 5^(3 - 6) = 5^-3 = 1/125
The third one down is rather sneaky. It's also kinda neat.
31 = 32 - 1 = 2^5 - 1
32 * 31
= 32 (2^5 - 1)
= 2^5(2^5 - 1)
= 2^10 - 2^5
= 1024 - 32
= 992
I don't see any math tricks to solve this. Use brute force.
6^5 * 5^-7 = 6^5 / 5^7 = 7776 / 17125 = 0.00953
2. Just pick a couple of questions out of the four above. The last one is a good example for division. The first one would be good for multiplication. I've explained all you need.

There is your answer! Please correct me if i'm wrong! :)
It is 2 because -2 was x and i knew y =2
