Question

If A union B = A iteraection B show that A = B

Answer 1

let ,A ={1,2,3} and B={1,2,3} then A union B is 1,2,3 and intersection also 1,2,3 Then A eqal B

Answer 2

Step-by-step explanation:

sopose A=(123)

B=(123)

A union B=(123) union (123) =(123)

A iteraection B=(123) iteraection (123)=(123)

A=B=(123)=(123)=(123)
