Given :

\sf{ \frac{ \sqrt{2 {}^{2}  }  \times  \sqrt[4]{256} }{ \sqrt[3]{64} } -  \bigg( \frac{1}{2} \bigg) {}^{ - 2}   } \\

First,

  • \sf{ \sqrt{2 {}^{2} } = 2 }
  • \sf{ \sqrt[4]{256} = 2 }
  • \sf{ \sqrt[3]{64}  =  \sqrt{8} }
  • \sf{ \bigg( \frac{1}{2} \bigg) {}^{ - 2}  = 4 } \\

Putting all values

\sf\longrightarrow{ \frac{2 \times 2}{ \sqrt{8} } - 4 } \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \sf\longrightarrow{ \frac{4 - ( \sqrt{8} \times 4) }{ \sqrt{8} } }  \\\\\sf\longrightarrow{ \frac{4 - 4 \sqrt{8} }{ \sqrt{8} } } \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \sf\longrightarrow{ \frac{4 - 4 \:  \cancel{ \sqrt{8}} }{ \cancel{ \sqrt{8}} } } \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \sf\longrightarrow{4 - 4} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \bf\longrightarrow \red{0} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

Answer:

Ans. -2

Step-by-step explanation:

 \sqrt{4}  \times   \frac{ \sqrt[4]{4 \times 4 \times 4 \times 4} }{ \sqrt[3]{4 \times 4 \times 4} }  -  { \frac{1}{2} }^{ - 2}  \\  \frac{2 \times 4}{4}  - (  { \frac{2}{1} }^{2} ) \\  =  \frac{8}{4}  -  {2}^{2}  \\  = 2 - 4 \\  =  - 2
