A) 25
B) 32
C) 9
D) 41
Correct Answer: D
Solution :
\[{{({{2}^{1/2}}+{{3}^{1/5}})}^{10=}}^{10}{{C}_{0}}{{({{2}^{1/2}})}^{10}}\] \[^{+10}{{C}_{1}}{{({{2}^{1/2}})}^{9}}({{3}^{1/5}})+.....{{+}^{10}}{{C}_{10}}{{({{3}^{1/5}})}^{10}}\] There are only two rational terms ? first term and last term. Now sum of two rational terms \[={{(2)}^{5}}+{{(3)}^{2}}=32+9=41\]You need to login to perform this action.
