Class 9 - Maths - Real Numbers - Problems on Rationalization (Part-2) For CBSE students

The video series provides solutions for typical problems related to rationalization of irrational numbers covered under chapter real numbers. The video covers the solution for a long type of answer based question.


If the product of two irrational numbers is a rational number, then each number is called the rationalization factor.

कक्षा - नवीं - हिंदी व्याकरण - वर्ण-विच्छेद (CBSE Class 9 Hindi Grammar - Varn Viched)(#eduvictors)(#class9Hindi)

हिंदी व्याकरण - वर्ण-विच्छेद

कक्षा - नवीं 

किसी शब्द में प्रयुक्त वर्णों को अलग-अलग करके लिखना ही वर्ण विच्छेद है। वर्ण-विच्छेद करते समय व्यंजनों को स्वर से अलग करके लिखा जाता है। इसका अर्थ है कि  वर्ण विच्छेद में हमें शब्दों को, जो की वर्णों के समूह हैं, अलग-अलग करना है या स्वर या व्यंजन को अलग-अलग करना है।

वर्ण विच्छेद करते समय ध्यान देने योग्य बातें:

1.  व्यंजन और स्वर को अलग करना आना चाहिए।

2.  वर्ण- विच्छेद करते समय व्यंजन के साथ लगी मात्रा को भी अलग करना चाहिए। जैसे:-

     क =  क् +अ

    का = क् ‌+ आ

    कि = क् + इ 

    की = क् + ई
