## Binomial theorem - Definition/Formula

For any positive integer n, the nth power of the sum of two numbers a and b may be expressed as the sum of n + 1 terms of the form.

The equation of binomial theorem is,

Where,

n ≥ 0 is an integer,

(n, k) is binomial coefficient.

The fully expanded form of higher exponents can also be calculated using the binomial expansion formula.
