The number of terms in the expansion of \((x+y+z)^{10}\) is
- A 66
- B 142
- C 11
- D 110
Answer & Solution
Correct Answer
(A) 66
Step-by-step Solution
Detailed explanation
We have,
\((x+y+z)^{10}\)
Total number of terms in the expansion of
\((x+y+z)^{10}={ }^{10+3-1} C_{3-1}={ }^{12} C_{2}=66\)
\((x+y+z)^{10}\)
Total number of terms in the expansion of
\((x+y+z)^{10}={ }^{10+3-1} C_{3-1}={ }^{12} C_{2}=66\)
