Question

Hello friends❤️​

I am going to ask a question of class 11th
subject :- maths
Chapter :- Set

Set is a collection of well defined objects .

A={x:x £ N , 5<=x=<6 }

Now tell me that, this statement is well defined or not.

Give me Ur views...​

Answer 1

Answer:

Yes, it is well defined.

Step-by-step explanation:

The presented set is in the form of set-builder, and clearly it is specifying that the elements of A are either equal to or greater than 5 and either less than or equal to 6.

So, A = { 5,6 }

Its elements are completely natural numbers too.

Hence, it is true.

Answer 2

A={x: x€N ,5<=x=<6}

in roaster form it can be written as

{5,6}

because x is equal to both 5 and 6 and between 5 and 6 no natural no. occurs

so it is well defined because it can be expressed in roaster form of set

if it was

A={x:x€N ,5<x<6}

then the set is null/void/empty set.

but still its well defined

in roaster form it will equal to

{} or phy
