If your expresion mean :
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 )
then :
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 ) =
- 4 * ( - 1 / 8 ) * ( - x ^ 4 ) =
( 1 / 2 ) * ( - x ^ 4 ) =
- x ^ 4 / 2
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 )
then :
( - 4 ) * ( - x ) ^ 3 * x * ( - 1 / 8 ) =
- 4 * ( - 1 / 8 ) * ( - x ^ 4 ) =
( 1 / 2 ) * ( - x ^ 4 ) =
- x ^ 4 / 2
