Question

A= [123456] B= [13579] then find A union B​

Answer 1

Answer:

AUB = {1,2,3,4,5,6,7,9}

Step-by-step explanation:

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

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

for union take all numbers from A and B set but don't repeat the number if numbers are common in both sets.

AUB = {1,2,3,4,5,6,7,9}

Answer 2

Given: A = {1,2,3,4,5,6} and B = {1,3,5,7,9}.

To find: The union of A and B.

Solution:

The two sets are given that is $A =[1,2,3,4,5,6]$ and $B = [1,3,5,7,9]$

For finding out the union of two sets we need to include all the values of the set $A$and set $B$ together in a single set, but we need to keep in mind that no value is written twice that is no value should be repeated.

The symbol of union is '∪'.

∴ A ∪ B = $[1,2,3,4,5,6,7,9]$

It is seen that no value is repeated in the union of the two given sets.

Final answer:

Hence, the union of A and B is $[1,2,3,4,5,6,7,9]$
