रिक्त समुच्चय से अनंत समुच्चय तक: चरण 3
This Class 10 Mathematics topic from the chapter Sets explains the concluding step used to show that a set is infinite. Students distinguish an empty set, which contains no elements, from an infinite set, whose elements do not end, and follow how a logical argument supports this conclusion. The topic strengthens understanding of set notation, membership, and mathematical reasoning, helping learners interpret why the existence of continually extendable elements rules out a finite count.
TOPIC PRACTICE
Up to 1 questions from this page. Select your focus, then start.
The first set has exactly two elements: the number 1 and the set {2, 3}. The second set has three elements: the numbers 1, 2, and 3. Although the inner set contains 2 and 3, it is itself one element of the first set; it is not automatically replaced by its members. Therefore the sets are not equal, and option B is correct.
