A U B =B U A
​

Answer 1

Answer:

{4,6}={4,6}

Step-by-step explanation:

first we find L.H.S

A U B={3,4,5,6}U{2,4,6}

={4,6}

R.H.S

B U A={2,4,6}U{3,4,5,6}

={4,6}

hence it is verified

Answer 2

Answer:

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

Step-by-step explanation:

GIVEN:

A={3,4,5,6}

B={2,4,6}

A U B = B U A ( we know that commutative law equal)

SOLUTION:

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

{2,3,4,5,6} = { 2,3,4,5,6 } ( in ascending order)
