Question

If A = {1, 2, 3, 4, 5} and B = {5, 6, 7, 8}, then A union nullset and A intersection nullset is ?​

Answer 1

Answer:

A ∪ { } = A

A ∩ { } = { }

Step-by-step explanation:

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

B = {5, 6, 7, 8}

To find:

A ∪ { } and A ∩ { }

A ∪ { } = {1, 2, 3, 4, 5} ∪ { } = A

∴ A ∪ { } = A and

A ∩ { } = {1, 2, 3, 4, 5} ∩ { } = { }

∴ A ∩ { } = { }
