Answer 1

$1 )\: \: \: \frac{ {4}^{5} }{ {4}^{11} }$

$= {4}^{5 - 11}$

$= {4}^{ - 6} \: \: ans$

$2) \: \: \frac{ { y}^{ - 13} }{ {y}^{ - 6} }$

$= {y}^{ - 13 - ( - 6)}$

$= {y}^{( - 7)}$

$3) \: \: {x}^{ {( - 3)}^{4} }$

$= {x}^{ - 12}$

$4) \: \: \: \frac{ {3}^{ - 3} { {3}^{ - 5} }^{?} }{ {3}^{ {( - 2)}^{3} } }$

$= \frac{ {3}^{( - 3 )+ ( - 5)} }{ {3}^{ - 6} }$

$= \frac{ { {3}^{ - 9} } }{ {3}^{ - 6} }$

$= {3}^{( - 9) - ( - 6)}$

$= {3}^{ - 3}$
