Chapter 8 Class 11 Binomial Theorem

NCERT Solutions of all questions, examples of Chapter 8 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 = a2 + b2 + ab

(a + b)3 = a3 + b3 + 3a2b + 3ab2

But what about big powers, like

(a + b)5


(a + b)9


(a + b)100


To find out these values, we use Binomial Theorem
