Answer 2

ANSWER = 1

$\Rightarrow \: \: \: \: \: ( {2}^{( - 1)} \times {4}^{( - 1)} ) \div( {2}^{( - 2)} )$

$\Rightarrow \: \: \: \: \: \: \: \: \:( {8}^{( - 1 - 1)}) \div ( {2}^{( - 2)} )$

$\Rightarrow \: \: \: {8}^{( - 2)} \div {2}^{( - 2)}$

$\Rightarrow \: \: \: {4}^{( - 2 -( - 2))}$

$\Rightarrow \: \: {4}^{ 0}$

$\Rightarrow \: \: 1$
