Class 10 Real Numbers | Q.3 | Prove that 1/√2, 7√5 and 6+√2 are Irrational | Exercise 1.2 NCERT
Welcome to Maths with Vinita Mam!
In this video, we solve Class 10 Real Numbers Chapter – Exercise 1.2, Question 3, which asks you to prove that certain numbers are irrational:

1. 1/√2 is irrational
2. 7√5 is irrational
3. 6 + √2 is irrational
We use the contradiction method to prove irrationality in each case, step by step. This concept is frequently tested in school exams and CBSE board papers. Understanding how irrational numbers behave and how to prove a number is irrational is fundamental to mastering Number Systems and Real Numbers at the Class 10 level.

This video is part of our complete NCERT Class 10 Maths series and follows the same format as our previous videos on Q.1 and Q.2 from Exercise 1.2.

If you're looking for a slow-paced, voice-over-ready visual explanation with pauses, this video is perfect for self-study and revision.
