In the (X-2) ^ 10 expansion, the sum of coefficients of all terms is equal to

In the (X-2) ^ 10 expansion, the sum of coefficients of all terms is equal to


fifty-eight thousand and twenty-five



(x+a)+(x+a)^2+(x+a)^3+…… +The sum of the coefficients of (x + a) ^ 10 expansion is equal to?


(x+a)+(x+a)^2+(x+a)^3+…… +(x+a)^10
Let x = 1, the sum of the coefficients of the expansion is obtained
S=(1+a)+(1+a)²+.+(1+a)^10
When a = 0, s = 10
When a ≠ 0, s = (1 + a) [(1 + a) ^ 10-1] / (1 + A-1)
=(1+a)/a[(1+a)^10-1]
