c =0 is the only possible case...when 2^2007 * k ( where is a int ) is a perfect square then c =0 if not take x to be integral part of sqrt 2^2007 * k c = 2^2007 * k - [ sqrt (2^2007 * k) ] ^2 convert into a^2 - b^2 we observe that the rhs is far greater than 2007 .. for any other value of x the difference will still be greater ...on simplifying we get { sqrt (2^2007 * k) } * 2 sqrt (2^2007 * k)sqrt (2^2007 * k) = 2^1003 * sqrt (2k)fractional part of sqrt of integer can be like x.0000n because its aquare can not give an integer so fractional part > 0.1 so therefore the equation above c = something gives a huge value... c =0 is the only possible answer..
