This chapter:    • The Binomial Theorem | JEE Maths Unit 5, C...   All lessons of this unit:    • JEE 2027 Maths | Unit 5 Binomial Theorem   How the binomial expansion turns surds into whole numbers: why the odd powers of root b cancel in (a+√b)^n + (a−√b)^n, why the difference is a multiple of root b, quick estimates with (1+x)^n 1+nx, and two solved JEE-style problems, including (√3+√2)^6 + (√3−√2)^6 = 970 by a faster squaring trick. Chapters 0:00 Introduction 0:36 Conjugates: half the terms cancel 2:36 Estimates: the first few terms are enough 3:58 Example 1: find (root 2 + 1)^6 + (root 2 - 1)^6 5:20 Example 2: find (root 3 + root 2)^6 + (root 3 - root 2)^6 7:45 Quick revision: conjugate sums, differences and estimates A free JEE paper every day and a full JEE Main mock every Sunday: https://rankdeterminant.com/go/yt-dai...
