Answer:We know that any odd positive integer is of the form 2q+1, where q is an integer. So, let x=2m+1 and y=2n+1, for some integers m and n.

Answer:We know that any odd positive integer is of the form 2q+1, where q is an integer. So, let x=2m+1 and y=2n+1, for some integers m and n. when have x²+y²

+=(2m+1)²+(2n+1)²

+=4m²+1+4m+4n²+1+4n

=4m²+4n²+4m+4n+2

+=4q+2when q= (+) + m+n

+y² is even and leave remainder 2

when divided by 4
