Using Direct Proof : Let’s assume n = 2x (using definitions of even numbers). n*n = (2x)(2x) = 2(2x*x) => n*n = 2(some integer). Therefore n*n is even. (x,y are some integers) KG answered Mar 5, 2023 • edited Mar 5, 2023 by KG KG comment Share Follow See all 0 reply Please log in or register to add a comment.
