A) \[150\]
B) \[148\]
C) \[152\]
D) \[146\]
Correct Answer: C
Solution :
At \[x=1,\] \[\left( 3+\frac{5}{x} \right)\,\left( 9-\frac{15}{x}+\frac{25}{{{x}^{2}}} \right)\] \[=\left( 3+\frac{5}{1} \right)\left( 9-\frac{15}{1}+\frac{25}{1} \right)\] \[=(3+5)\,(9-15+25)\] \[=8\times 19=152\]You need to login to perform this action.
