In this video, we solve Question 21 from the CBSE Class 10 Maths 2026 paper.

This is a 2-mark question with an OR choice, where students can solve either of the two options:

• Prove that 2 + 3√5 is an irrational number
• Find m using Euclid’s Division Lemma for HCF

To help students prepare better, both options are solved step-by-step, so you can understand whichever concept appears in your exam.

This question tests:

✔ Proof of irrational numbers
✔ Euclid’s Division Lemma
✔ HCF representation concept

These are very common 2-mark questions in CBSE board exams, so understanding the method is important.
