Hi please could anyone help me with this homework question?
i...Determine the elements of the sets
A={x | x\varepsilon N, 2 < x ≤ 5}
B={n | nN, n=x+3, x \varepsilon A}
ii...Given that n(AxB) = n(A) x n(B) what is the value of n(AxB) .
Thanks

Why not learn to post in symbols? You can use LaTeX tags
[tex]B=\{n: n\in N,~n=x+3,~x\in A\}[/tex] gives $\displaystyle B=\{n: n\in N,~n=x+3,~x\in A\} $.
Just add 3 to each term if $\displaystyle A $
