Answer 2

Answer:

$A\cup B={1,2,3,4,5,6,7}$

Step-by-step explanation:

Given : A=(1,2,3,4,5), B=(5,6,7)

To find : $A\cup B$

Solution :  

In the field of sets, $A\cup B$ denotes the union of the two sets A and B.

This means that the element present in $A\cup B$ should be a part of either A or B.

We have given,

A=(1,2,3,4,5), B=(5,6,7)

$A\cup B={1,2,3,4,5,6,7}$

Therefore, $A\cup B={1,2,3,4,5,6,7}$
