Question

Write the following set in listing method: A = {x / x E N, 5 < x < 7}​

Answer 1

Given : A  = { x :  x  ∈ N , 5 < x < 7}

To Find : Write the  set in listing method:

Solution:

A  = { x :  x  ∈ N , 5 < x < 7}

Set is in set builder form

To write set in listing form all elements need to be find first

x  ∈ N

Hence x is natural number

 5 < x < 7

There is only one natural number   x = 6

which satisfy the above inequality

Hence  set in  listing form is

A = { 6 }

n(A) = 1

Cardinality of set A is 1
