Here A={x is a natural numberandfactor of 18}.

={1,2,3,6,9,18}A={x is a natural numberandfactor of 18}

={1,2,3,6,9,18}andB={x is a natural numberand less than 6}

={1,2,3,4,5}.B={x is a natural numberand less than 6}={1,2,3,4,5}

Therefore,
AB andAB={1,2,3,4,5,6,9,18}={1,2,3}.
AB={1,2,3,4,5,6,9,18}
and
AB={1,2,3}.
