Question

If T = {1, 2, 3, 4, 5} and M = {3, 4, 7, 8} then T U M = ? *

Answer 1

Answer

T ∪ M = {1, 2, 3, 4, 5, 7, 8}

Step by step explanation

Given , the sets

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

M = { 3, 4, 7, 8}

Now we have

T ∪M

= { 1, 2, 3, 4, 5} ∪{ 3, 4, 7, 8}

= { 1, 2, 3, 4, 5, 7, 8}

Extra information about Union of sets

★Definition : Let us consider two non empty set A and B . The union of sets A and B is a set which consists of all the elements of A and all the elements of B , common elements being taken only once .

• Symbolically union is written as ∪
• For example 'A ∪B' is read as 'A union B' .

Answer 2

Answer:

Given:

T = [ 1,2,3,4,5]

M = [3,4,7,8]

Now, we have.

T * M

[ 1,2,3,4,5] * [3,4,7,8]

[ 1,2,3,4,5,7,8]
