Arre, beta! Assume root 2 rational, so you write it as p/q, reduced! Then square both sides...p²=2q². This means p² is even, so p is even. But then q becomes even too...contradiction ho gaya because you said p/q was reduced! Theek hai na? Bas, exam mein aise likhna!
Yeh padhte time mujhe apne beta ki fees ki tension aati hai...par sochta hoon, isi tarah ek clear, solid proof se uska future bhi strong hoga! Chalo, padhle sahib!
