Question

prove that (A - B) - C = A - ( B- C)

*this is a question of sets, pls answer it in that context​

Answer 1

Answer:

( A - B ) - C = A - ( B - C )

Let's prove that with one example :-

Let : A = 12 , B = 5 , C = 3

( A - B ) - C = A - ( B - C )

( 12 - 5 ) - 3 = 12 - ( 5 - 3 )

7 - 3 = 12 - 2

4 is not equal to 10

Hence LHS is not Equal to RHS !!

So we cannot prove that both are equal .

Hope it helps to you!!
