is:
Text Solution
Verified by ExpertsThe correct answer is:
B
To find the sum of all rational terms in the expansion of 
, we consider the binomial expansion:
We need to identify and sum only the rational terms. In the binomial expansion, a term is rational if the exponent of 
is even.
Thus, the rational terms are:
Evaluating these terms:
Summing these rational terms gives:
Therefore, the sum of all rational terms in the expansion is 18,817.
