Question #1b0f0

Answer 1

`6553600`

Explanation:

1st doubling`->100xx2`

2nd doubling`->100xx2xx2`

3rd doubling`->100xx2xx2xx2`

Let the count of hours be `n`

Then if it doubled every hour we would have:

`100xx2^n`

However, it doubles every 15 minutes. There are 4 lots of 15 minutes in every hour so the calculation cycle is:

`100xx2^(4n)`

So for 4 yours we have:

`100xx2^(4xx4)=100xx2^(16)=6553600`
