QUESTION 6 1. 2 Give a direct proof that if n is even, then n is even. [Hint: Consider whether n? +n is odd or even and from

Answer 1

Answer #1

Proof that if ne is even , then in is even even, Assume that n² is not n is odd Then could write it we е. as akt L (2K+ 1)2 =

so if is even then n must be even.
