Question

If A=(1,2,3,4);B=(1,2,3,4,5,6,7,8,)then find AUB,BUA⁰.What do you notice about the result
​

Answer 1

Answer:

A = {1,2,3,4} , B = {1,2,3,4,5,6,7,8}

a union b = {1,2,3,4,5,6,7,8} => single apperance of any element of both sets, only singke apperance

a intersection b = {1,2,3,4} => common in both sets

Step-by-step explanation:

notice about result is

if the small set is subset of big set, then union of both set is big set and intersection of both set is small set

i hope you understand
