Answer:
#1
[tex]{ \tt{ {( \frac{ {2x}^{ - 1} }{ {4x}^{2} } )}^{ - 3} }} \\ \\ = { \tt{ {( \frac{ {x}^{( - 1 - 2)} }{2}) }^{ - 3} }} \\ \\ = { \tt{ ({ \frac{ {x}^{ - 3} }{2}) }^{ - 3} }} \\ \\ = { \tt{( \frac{ {x}^{( - 3 \times - 3)} }{ {2}^{ - 3} } }}) \\ \\ ={ \boxed{ \mathfrak{answer : { \tt{ {b. \: 8 {x}^{9} }}}}}}[/tex]
#2
[tex]{ \tt{ \frac{16 {x}^{3} - {4x}^{2} + 44x - 60 }{4x} }} \\ \\ { \boxed{ \mathfrak{answer : \: { \tt{b. \: 4 {x}^{2} - x + 11 - \frac{15}{x} }}}}}[/tex]
