Answer 2

Answer:

${2}^{ - 1}$

Step-by-step explanation:

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

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

$\frac{1}{8} \div \frac{1}{4}$

$\frac{1}{8} \times \frac{4}{1}$

cancelling 8 by 4 ,we get 2

that is

$\frac{1}{2}$

therefore answer

$\frac{1}{2}$

which can also be written as

${2}^{ - 1}$
