5. How did the Binomial theorem originate and what are the applications of the binomial theorem in Chapter 7 of Class 11th Maths?
The binomial theorem is known to the world from the fourth century BC. This is when the Greek mathematician Euclid used the binomial theorem for the exponent having the value two. However, the usage of the value three was in the sixth century in India. The Binomial theorem's application is to find the reminder, to find the digit of a number, test of divisibility and the comparisons of the number. Students can learn more about this from Vedantu’s Important Questions.
