Question

If A ={Prime factors of 18} and B={Prime factors of 45},find (A U B) and A ~B (A intersection B)​

Answer 1

Step-by-step explanation:

A={2,3}

B={5,3}

(A U B)={2,3,5}

A~B ={3}

Answer 2

Answer:

AUB=(2,3,5) AND A ~B=(3)

Step-by-step explanation:

HERE PRIME FACTORS 0F 18=2,3

PRIME FACTORS OF45=3,5

A={2,3}

B={3,5}

A U B ={2,3} U {3,5}

={2,3,5}

A~B (A INTERSECTION B)

={2,3}~{3,5}

={3}

THEREFORE

AUB={2,3,5}

A~B={3}
