Question

a set B consists of all natural numbers (counting numbers) less than or equal to 100. Use set-builder notation to define B.

Answer 1

Answer:

B={x:$x\leq 100, x\in N$}

Step-by-step explanation:

We are given that a set B consist of all natural numbers ( counting numbers) less than or equal to 100.

We have to write given set in set builder notation.

Let x be the element belongs to natural number.

Then , the set B in set builder form can be written as

B={x:$x\leq 100, x\in N$}

Hence, the set builder form of given set is given by

B={x:$x\leq 100, x\in N$}

Answer:B={x:$x\leq 100, x\in N$}

Answer 2

Answer:  The required set-builder notation is :

$B=\{x:x\epsilon \mathbb{N},x\leq 100\}.$

Step-by-step explanation:  We are given to write the following set B in set-builder form :

the set B consists of all natural numbers less than or equal to 100.

In set-builder form, a variable x is used to represent each and every element of the set.

Therefore, the set B in set-builder form can be written as :

$B=\{x:x\epsilon \mathbb{N},x\leq 100\}.$

Thus, the required set-builder notation is :

$B=\{x:x\epsilon \mathbb{N},x\leq 100\}.$
