Answer 1

sorry I didn't know the answer

Answer 2

Answer:

are so easy

Step-by-step explanation:

are you in 9th class

the question is of alegebra first chapter sets

n ( A intersection B ) means

the no. which come I. both sets

eg. set A = { 1 , 2 , 3 ,4}

and set B ={ 5 ,6 ,8,4}

so here 4 is common so it comes in both

so it is called

n ( A intersection B )

and n { A union B }

means the no. which comes in whole set

such as e.g natural number are set N = {1, 2,3,4,5,6}

and set of A { 1,2,3,8,9}

so here 1,2,3,8,9 are also natural no. so

set N is. a universal set

so it is called as n { N union A}

plz thank my answer and make me brainlest plz yaar
