A) 0.4
B)
C) 0.04
D) 0.004
Correct Answer: B
Solution :
\[{{(\sqrt[3]{0.004096})}^{\frac{1}{2}}}={{(0.004096)}^{\frac{1}{3}\times \frac{1}{2}}}\] \[={{\left( \frac{4096}{1000000} \right)}^{\frac{1}{6}}}={{\left\{ {{\left( \frac{4}{10} \right)}^{6}} \right\}}^{\frac{1}{6}}}={{\left( \frac{4}{10} \right)}^{6\times \frac{1}{6}}}=\frac{4}{10}=0.4\]
