Answer:

Hey Mate,

Given Data,

U = {1, 2, 3, 4, 5, 6, 7, 8, 9}

A = {2, 4, 6, 8}

B = {2, 3, 5, 7}

A' = {1, 3, 5, 7, 9}

B' = {1, 4, 6, 8, 9}

So, (A' n B') =  {1, 9}

(A U B)' = U - (A U B)

(A U B)' = {1, 2, 3, 4, 5, 6, 7, 8, 9} - {2, 3, 4, 5, 6, 7, 8}

(A U B)' = {1, 9} = (A' n B')

Answer 2

$\huge\star\mathfrak\blue{{Answer:-}}$

U = {1, 2, 3, 4, 5, 6, 7, 8, 9}

A = {2, 4, 6, 8}

B = {2, 3, 5, 7}

A' = {1, 3, 5, 7, 9}

B' = {1, 4, 6, 8, 9}

So, (A' n B') = {1, 9}

(A U B)' = U - (A U B)

(A U B)' = {1, 2, 3, 4, 5, 6, 7, 8, 9} - {2, 3, 4, 5, 6, 7, 8}

(A U B)' = {1, 9} = (A' n B')
