Question

If A = {1,2,3,4} ; B = {3,5,7,9} then find AAB.​

Answer 1

Answer:

A={2,4,6,8,10}

B={1,3,5,7,9}

A−B={2,4,6,8,10}−{1,3,5,7,9}={2,4,6,8,10}

Answer 2

Answer:

A={1,2,3,4,}; B={3,5,7,9}

AAB= {1,2,3,4,5,7,9,}

because if we can write the elements of A and B

that will not effect the answer
