CBSE Class 9 - Real Numbers - Problem on Rationalisation (Part-3)

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 denominator of an expression is a surd, it can be reduced to an expression with rational denominator.

If the product of two surds is a rational number, then each one of them is a rationalizing factor of the other.

In this series, we'll try to present solutions for more HOTS and typical problems.

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. The process of multiplying an irrational number by its rationalising factor is called rationalisation. In this series, we'll try to present solutions for more HOTS and typical problems.

 

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
