I know the answer ( i.e., {g,h}
I need an explanation please​

Answer 1

Step-by-step explanation:

Example 1: If A = {1, 2, 3, 4} and B = {2, 3, 6, 7} then find A U B.

Solution:

To find: A U B.

Given that:

A = {1, 2, 3, 4}

B = {2, 3, 6, 7}

By using the A union B formula, we find A U B just by writing all the elements of A and B in one set by avoiding the duplicates.

So, A U B = {1, 2, 3, 4} U {2, 3, 6, 7} = {1, 2, 3, 4, 6, 7}

Note: The elements in the answer set do not need to be in order. 

Answer: A U B = {1, 2, 3, 4, 6, 7}.

Answer 2

Answer:

(AUB) = {a,b,c,d,e,f}

It is not {g,h}
