what do you mean by square?
powers of 2 are numbers like
2^2, 2^3, 2^4 ... etc or
2,4,8,16,32,64 128 256 512 1024 ..
Now, which of those lie between 100 and 200 ?
BTW, before the size of memory chips got out of hand, they used to come in 128 MB, or 256 MB, etc
I am using a 512 MB chip in my Nikon camera.
2^2, 2^3, 2^4 ... etc or
