Question

Let A = {2,4,6,8,...}, B = {1,3,5,7,.....} then find (A-B)u(B- A)​

Answer 1

AUB = {1,2,3,4,5,6,7,8,9,......}. which means AUB belongs to natural number

Answer 2

Answer:

{1,2,3,4,5,...}

Step-by-step explanation:

A-B = {2,4,6,8,...} - {1,3,5,7,.....} = {2,4,6,8,...}

B-A = {1,3,5,7,.....} - {2,4,6,8,...} = {1,3,5,7,.....}.

[In both the above operations nothing will be subtracted since one set is of Even natural numbers and other set of odd natural numbers. Since no element is common in them, nothing will be changed in initial set].

(A-B) U (B-A) = {2,4,6,8,...} U {1,3,5,7,.....} = {1,2,3,4,5,...}
