Answer 2

Given; A={x/x ∈ N, x is a factor of 6}

B={x/x ∈ N, x is a factor of 8}

To Find; A-B & B-A

Solution; A={x/x ∈ N, x is a factor of 6}

A ={ 1,2,3,6}

B={x/x ∈ N, x is a factor of 8}

B={1,2,4,8}

A-B means B is subtracted from A that is the elements of B are subtracted from A

A-B = {3,6}

B-A means A is subtracted from B is the elements of A are subtracted from B

B-A={ 4,8}

Hence A-B = {3,6} and B-A={ 4,8}
