Question

A={1,2,3,4,5,6},B={3,4,6,7,8} then find (a-b) U (b-a)

Answer 1

Answer:

∴ (A-B) U (B-A) = { 1,2,5,7,8}

Step-by-step explanation:

Given,

A={1,2,3,4,5,6}

B={3,4,6,7,8}

(A-B) ={1,2,3,4,5,6} -  {3,4,6,7,8}

      = { 1,2,5}

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

       = { 7,8}

∴ (A-B) U (B-A) = { 1,2,5} U  { 7,8}

                     = { 1,2,5,7,8}
