Prove that any number of the form 4n+2 can never be a perfect square.
Asked by mehaksaini | 4th Feb, 2010, 11:17: AM
where n is a natural number.
so then, 2n+1 will be an odd number.
so it won't have 2 as a factor.
so 2(2n+1) will not have all factors which are repeated, which is necessary for 4n+2 to be a perfect square.
hence the answer.
