Which term is greater (1, 2)4000 or 800? |
|
Answer» (1, 2)4000 = (1 + 0.2)4000 Now, expanding by binomial theorem, we get (1 + 0.2)4000 = 4000 C0 (1)4000 (0.2)0 + 4000 C1 (14000 – 1 (0.2)1 +4000 C3 (1)4000 – 3 (0.2)3 + … = 1 + 4000(0.2) + other terms of the expansion = 1 + 800 + other terms of the expansion = 801 + other terms of the expansion Hence, (1, 2)4000 > 800 |
