Multiple Choice

Given the derivative below find the requested higher-order derivative. $f ^ { tt } ( x ) = 8 x ^ { \frac { 7 } { 5 } } , f ^ { ( i v ) } ( x )$

A) $f ^ { ( i v ) } ( x ) = - ( 56 / 5 ) x ^ { 2 / 5 }$
B) $f ^ { ( i v ) } ( x ) = ( 112 / 25 ) x ^ { 2 / 5 }$
C) $f ^ { ( i v ) } ( x ) = ( 112 / 25 ) x ^ { \frac { - 3 } { 5 } }$
D) $f ^ { ( i v ) } ( x ) = ( 56 / 5 ) x ^ { 2 / 5 }$
E) $f ^ { ( i v ) } ( x ) = - ( 112 / 25 ) x ^ { \frac { - 3 } { 5 } }$
