Question

Represent the given set in listing method:
A = { x: x < 10 , x ϵ N.}​

Answer 1

Explanation : -

A = { x : x < 10 , x ∈ N }

Given set A contains all the values of x for which x is smaller than 10 where x belongs to natural numbers. N is the ab to represent set of all natural numbers.

Natural numbers smaller than 10 are : 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 and 9.

So the set A in listing form is :-

A = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 }

This form of representation of set is also known as roaster form or tabular form.
