] | Asserting that an integer is even is the same thing as asserting that it is twice *another integer*. So, since $2k^2$ is an integer, $2(2k^2)$ is an even integer. But $n^2=2(2k^2)$. | Because n is even we can write it of the from $n=2k$ where k is an integer (because if n is even then $\frac{n}{2}$ must be integer. As you have written in the proof $n^2=2(2k^2)$, and because of the fact $2k^2$ is an integer, 2 multiplied by an integer must be even.
Hopefully that helps you :) |
