# In Exercise 14-35, prove each statement. A     ∩     ( B − A ) =     ∅

To determine

To prove: A(BA)=ϕ

Explanation

Formula used:

1) Intersection:

If A and B are sets, the intersection of A and B is the set AB ( read as‘ A intersection B ’) given by, AB={x|xAandxB}

2) Complement:

For arbitrary subsets A and B of the universal set U, the complement of B in A is AB={xU|xAandxB}

Proof:

Use definition of complement,

BA={xU|xBandxA}

By using definition of intersection,

A(BA)={xA}
