What Does the Sum of Coefficients in the Binomial Theorem Expansion Represent?

Click For Summary
SUMMARY

The sum of the coefficients in the binomial theorem expansion of (1+x)n is determined by substituting x with 1. This results in the expression simplifying to 2n, which represents the total number of subsets of a set with n elements. This fundamental concept is crucial for understanding combinatorial mathematics and the properties of binomial coefficients.

PREREQUISITES

TL;DR
Stuck at understanding binomial thorem.
In the general expansion of (1+x)^n what does the sum of the coefficients mean?
