Question

A={1,3,5,7,} B= {5,9,13,15,} C= {1,3,4,13}find (A-B)-C​

Answer 1

a-b={1,3,7}

(a-b)-c={7}

Answer 2

Answer:

(A-B)-C = {7}

Step-by-step explanation:

Here,

A = {1,3,5,7}

B = {5,9,13,15}

C = {1,3,4,13}

Now,

A-B = {1,3,5,7} - {5,9,13,15}

= {1,3,7}

So,

(A-B)-C = {1,3,7} - {1,3,4,13}

= {7}
