Answer:
The representation of the set {x : x is a multiple of 3, x€N }
In descriptive form: {The natural numbers which are multiples of 3}
In roster form: {3,6,9,12,..................}
Step-by-step explanation:
Let A be the set {x : x is a multiple of 3 , x€N }
Here the set is represented in the set builder form.
Required to represent the set in descriptive form and roster form
Solution:
In the descriptive form, the elements of a set are represented as a statement enclosed inside the curly brackets
Then the set A can be expressed in descriptive form as
A = {The natural numbers which are multiples of 3}
In the roster form, the elements of the set are listed separated by a comma and enclosed in curly brackets
Then, set A can be represented in roster form as
A = {3,6,9,12,..................}
∴The representation of the set {x : x is a multiple of 3, x€N }
In descriptive form: {The natural numbers which are multiples of 3}
In roster form: {3,6,9,12,..................}
