NCERT Solutions of all questions, examples of Chapter 7 Class 11 Binomial Theorem available free at teachoo. You can check out the answers of the exercise questions or the examples, and you can also study the topics.

Let's see what is binomial theorem and why we study it.

We know that

(a + b) 2 = a 2 + b 2 + ab

(a + b) 3 = a 3 + b 3 + 3a 2 b + 3ab 2

But what about big powers, like

(a + b) 5

or

(a + b) 9

or 

(a + b) 100

 

To find out these values, we use Binomial Theorem

 

The topics in this chapter include
