**Thm-1;** Whats the sum of the coefficients in the expansion .. ..

In use x=1.

Then we have **sum-of-****all-coefficients** = .

Also total possible combinations of n things is .

**Thm-2; **In the above expansion the sum of odd coefficient is same as the sum of even coefficient. put x=-1, then from above;

1+∑**even- coefficients** = ∑**odd-coefficients **= 1/2(∑**all-coefficients**) =
