Question

If A = {1,2,3,4} and B = {1,2,3,4,5,6,7} find B - A​

Answer 1

Given that:

A={1,2,3,4},B={3,4,5,6} and C={6,7}

A∩B={3,4}

L.H.S.=(A∩B)∩C={ϕ}

Now,

B∩C={6} and

R.H.S.=A∩(B∩C)={ϕ}

∴L.H.S=R.H.S

Answer 2

Answer:

❥ Given that:

A={1,2,3,4},B={3,4,5,6} and C={6,7}A∩B={3,4}

L.H.S.=(A∩B)∩C={ϕ}

Now,

B∩C={6} and

R.H.S.=A∩(B∩C)={ϕ}

∴L.H.S=R.H.S
