A) \[6\sqrt[3]{2}\]
B) \[6\sqrt[4]{2}\]
C) \[6\sqrt[5]{2}\]
D) \[16\sqrt[4]{2}\]
Correct Answer: D
Solution :
(d): \[7{{\left( 81\times 2 \right)}^{1/4}}-5{{\left( 16\times 2 \right)}^{1/4}}+{{\left( 625\times 2 \right)}^{1/4}}\] \[\Rightarrow 21{{(2)}^{1/4}}-10{{(2)}^{1/4}}+5{{(2)}^{1/4}}\] \[\Rightarrow {{(2)}^{1/4}}\left( 21-10+5 \right)=16\sqrt[4]{2}\]You need to login to perform this action.
