Question

if A={1,2,4} B={2,4,6} C={2,6} then find {A-B}*{B-C}​

Answer 1

Answer:

A-B={ 1,2,3} -{2,4,6}

A-B=. { 1,3,4,6}

B-C={2,4,6}-{2,6}

B - C= {4}

Answer 2

The value of $(A-B)(B-C)$is {1, 2}.

Explanation:

We have,

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

To find, $(A-B)(B-C)$ = ?

∴ $A-B=[1,2,4]-[2,4,6]=$ {1} and

B - C = {2, 4, 6} - {2, 6} = {2}

∴$(A-B)(B-C)=${1} × {2} = {1, 2}

Hence, the value of $(A-B)(B-C) is${1, 2}.
