Question

if m and n are are positive numbers then m square + n square is even but not divisible by 4. Justify?​

Answer 1

Answer:

If m and n are odd positive integers, then m2 + n2 is even, but not divisible by 4. Justify. ... Since m is odd positive integer then we can write m=2a+1 and n=2b+1, such that a,b >0 m2+n2=(2a+1)^2+(2b+1)^2 = 4a^2+1+4a+4b^2+1+4b = 4a^2+4b^2+4a+4b+2 = 2(2a^2+2b^2+2a+2b+1) Above eqn is divisible by 2 but not divisible by 4.28-Jan-2018
