In this video, we explain why √2 (Square Root of 2) is an Irrational Number in a clear, step-by-step manner, strictly based on the Class 10 CBSE Maths syllabus.
🔹 Assume √2 = a/b, where a and b are coprime integers
🔹 Square both sides and apply the contradiction method
🔹 Understand why this assumption leads to a contradiction
🔹 Conclude that √2 cannot be a rational number
This video is helpful for:
