perform the given operation.
Let U = {1,2,3,4,5,6,7,8,9,10}
enter the answer
{1,2,8} U 2,8,9}
no idea? list the elements that appear at least once in the combined list.
{1,2,8,9}
we have a winner!
To perform the given operation {1,2,8} U {2,8,9}, we need to combine the elements from both sets while removing any duplicates.
First, let's write down the sets in set-builder notation to make it clearer:
Set A = {1, 2, 8}
Set B = {2, 8, 9}
To find the union of two sets, we combine all the elements from both sets without repeating any duplicates.
The final set, which is the union of A and B, can be written as:
A U B = {1, 2, 8, 9}
Therefore, the answer to the operation {1,2,8} U {2,8,9} is {1, 2, 8, 9}.
