How to find the sum of the coefficients of binomial? How to find the sum of the coefficients in the expansion? What's the difference?
Sum of binomial coefficients = 2 ^ n
The sum of the coefficients in the expansion can be obtained by the assignment method, so that x = 1
For example: (2 + x) ^ n the sum of the coefficients in the expansion is 3 ^ n
What is Newton's binomial formula
For Newton's extraordinary discovery, we can only have a glimpse here. First of all, we introduce Newton's first mathematical discovery binomial theorem. Although according to the concept of Euclid or Archimedes, this is not a "theorem", because Newton did not provide complete proof. However, his insight and intuition are enough to make him
