Question

If A × B = {(2, 6), (1, 8), (2, 4), (1, 4), (1, 6), (2, 8)}, then set A is equal to

Answer 1

Answer:

A={1,2}

Step-by-step explanation:

A×B is defined as the set of (a,b) where a is an element of set A and B is an element of set B.

From the given set of A×B,

The values of a are 2,1,2,1,1,2

That is the distinct values of a are 1,2.

So, the elements in set A are 1 and 2

Hence, the set A={1,2}

Hope this helps!

Answer 2

Answer:

A={1,2}

Step-by-step explanation:

A is define as a set of ( a,b) where a=A, b=B

Frome the given set a×b ={(2,6),(1,8),(2,4),(1,4),(1,6),(2,8)}, in all this set you will notice that in every set like (a,b) every first no. is 1 or 2

So,the answer for this Q is 1,2
