In earlier classes, we have learnt how to find the squares and cubes of binomials like a + b and a-b. Using them, we could evaluate the numericals values of number like (98) ^{ 2 }=(100-2)^{2},(999) ^{ 3 }=(1000-1)^{3}etc. However, for higher powers like (101)^{ 5} ., the calculations become difficult by using repeated multiplication.This difficulty was overcome by a theorem known as binomial theorem. It gives an easier way to expand (a+b),where n is an integer or a rational number. In this chapter, we study binomial theorem for positive integral indices only.
