#6553600#

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#
