Question

If A= {2.3.5), find AU Φ and ΦUA and comment on results​

Answer 1

Step-by-step explanation:

Given :-

A = { 2,3,5}

To find :-

Find AU Φ and ΦUA and comment on results ?

Solution :-

Given that

A = { 2,3,5}

We know that

Φ = { }

Now,

AU Φ = {2,3,5} U { }

=> A U Φ = { 2,3,5} -----------(1)

and

ΦUA = { } U { 2,3,5}

=> ΦUA ={ 2,3,5} -------------(2)

From (1)&(2)

AU Φ = ΦUA

Where Φ is the Identity set in the Union of the non-empty sets .

Answer:-

→ A U Φ = { 2,3,5}

→ ΦUA ={ 2,3,5}

→ AU Φ = ΦUA

Used formulae:-

→ Φ is the empty set and it is represented by { }

→ AUB is the set of all elements either in A or in B or in both sets .

→ Φ is the Identity set in the Union of the non-empty sets.

Answer 2

Step-by-step explanation:

AU and UA both are same so their is no difference in them I hope this was helpful
