Question

If €= {1,2,3,4,5,6,7,8,9,10}. A = {1,4,7,9} B={2,4,6,7,8}
Prove
A' union B '= {A intersection B}'​

Answer 1

Given -

Universal set = {1,2,3,4,5,6,7,8,9,10}

A = {1,4,7,9}

B = {2,4,6,7,8}

Proving -

A' union B' = {A intersection B}'

{3,5} = {3,5}

Hence it is proved that A' U B' = {A∩B}'
