Welcome to Maths with Vinita Mam!
In this video, we prove that 5 − √3 is irrational with a complete step-by-step explanation from Class 10 NCERT Maths – Real Numbers – Exercise 1.2.

The question “Prove that 5 − √3 is irrational” is a frequently asked board-level proof. We solve this using the contradiction method to show that if 5 − √3 were rational, it would imply that √3 is rational — which contradicts a well-known fact.

In this video: ✅ We assume 5 − √3 is rational
✅ Rearrange the expression
✅ Derive √3 as a rational form
✅ Show contradiction
✅ Conclude that 5 − √3 must be irrational

This video proves that 5 − √3 is irrational clearly, slowly, and visually using logical reasoning that follows CBSE’s marking scheme.
