WebOur First Proof! 😃 Theorem: If n is an even integer, then n2 is even. Proof:Let n be an even integer. Since n is even, there is some integer k such that n = 2k. This means that n2 = (2k)2 = 4k2 = 2(2k2). From this, we see that there is an integer m (namely, 2k2) where n2 = 2m. Therefore, n2 is even. This symbol means “end of proof” This ...
