A) 3/2
B) 5/4
C) 5/2
D) None of these
Correct Answer: B
Solution :
\[(10-r)\left( \frac{1}{2} \right)+r(-2)=0\Rightarrow 5-\frac{r}{2}-2r=0\Rightarrow r=2\] So the term independent of x \[{{=}^{10}}{{C}_{2}}\times {{\left( \frac{1}{3} \right)}^{4}}{{\left( \frac{3}{2} \right)}^{2}}=\frac{10\times 9}{2\times 1}\times \frac{1}{3\times 3\times 2\times 2}=\frac{5}{4}\]You need to login to perform this action.
