TS EAMCET · Maths · Binomial Theorem
The sum of the coefficients in the expansion of is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
To find the sum of coefficients, replace all the variables with 1. Here x is the only variable, so put, x=1. Therefore, we get, Sum of coefficients = 1+1212=3212
