Write the converse of the statement:'If a number n is even, then `n^2` is even.'

Explanation

Components are:
.(q): (x). is an integer and .(x)^(2). is even . (r): (x). is even .sim r rarr x. is odd .rarr x=2 n+1. for some integer .n. .rarr (x)^(2)=(2 (n)+1)^(2) rarr (x)^(2)=4 (n)^(2)+4 (n)+1., is odd
.rarr sim q. is true. . therefore. the given statement is true .(because 4 n^(2).. and .4 n. are even .4 n^(2)+4 n+1. is odd .).
