A) \[136x{{y}^{7}}\]
B) \[136xy\]
C) \[-136x{{y}^{15/2}}\]
D) \[-136x{{y}^{2}}\]
Correct Answer: C
Solution :
\[{{T}_{16}}={{\,}^{17}}{{C}_{15}}{{(\sqrt{x})}^{2}}{{(-\sqrt{y})}^{15}}\] \[=-\frac{17\times 16}{2\times 1}\times x{{y}^{15/2}}=-136x{{y}^{15/2}}\]You need to login to perform this action.
