a=3q+r, 0 is lesser than or equal to r < 3 a^2 =(3q)^2 or (3q+1)^2 or (3q+2)^2 (3q)^2 = 9q^2 =(3*3q)^2 = 3k1 [k1=3q^2] (3q+1)^2= 9q^2 +6q+1 = 3(3q^2 +2q)+1 = 3k2+1 [k2=3q^2+3q] (3q+2)^2 = 9q^2+12q+4 =9q^2+12q+3+1 =3[3q^2+4q+1]+1 =3k3 + 1 (k3=[3q^2+4q+1]) Therefore square of any positive integer is either of the form 3m or 3m+1 Note: those k1, k2 and k3 the constants should be written below the variable k.
