if `A= {x:x in N `, x is a factor of 12 } and B={x:x in N`, x is a factor of 18}, Find `A cap B`. |
Answer» We have , `A{x :x in N, x " is a factor of 12} ={1,2, 3,4, 6, 12}`, `B={x:x in N, x " is a factor of 18}={1,2,3, 6,9, 18}`. `therefore A cap B= {1,2,3,4,6, 12 } cap {1,2,3,6,9, 18) ={1,2,3,6}`. |
