Answer 1

Answer:

$( {2}^{ - 3} - {2}^{ - 4} )( {2}^{ - 3} + {2}^{ - 4} )$

$= ( \frac{1}{ {2}^{3} } - \frac{1}{ {2}^{4} } )( \frac{1}{ {2}^{3} } + \frac{1}{ {2}^{4} } )$

$= ( \frac{1}{8} - \frac{1}{16} )( \frac{1}{8} + \frac{1}{16} )$

$= \frac{1}{16} \times \frac{3}{16} = \frac{3}{256}$

Answer 2

Answer:

$( {2}^{ - 3} - {2}^{ - 4} )( {2}^{ - 3} + {2}^{ - 4} ) \\ = ( \frac{1}{2}^{ 3} - { \frac{1}{2} }^{4} )( { \frac{1}{2} }^{3} + { \frac{1}{2} }^{4} ) \\ = ( \frac{1}{8} - \frac{1}{16} )( \frac{1}{8} + \frac{1}{16} ) \\ = ( \frac{2 - 1}{16} )( \frac{2 + 1}{16} ) \\ = ( \frac{1}{16} )( \frac{3}{16} ) \\ = \frac{3}{256}$
