Answer:
1. 2^28
2. 3 times more
Explanation:
Since we know that he did 2^6 for 6 2's. We know that 28 days would equal to 2^28.
I never knew how many coins Andre had so I would say 3 times more.
For the first one, I'm guessing 2 to the 28th power. It was 2 to the 6th power on the 6th day, so 28 on the 28th day.
I don't think I have all the info for #2, sorry.
