Simplify expression show work please

4* cube root ( 16x ) - 2* cube root ( 128 x)

factoring 16 we get 2*2*2*2

cube root 16 x = 2 cube root ( 2x )

factoring 128 we get 2*2*2*2*2*2*2

cube root 128x = 4 cube root ( 2x )

so the expression becomes

4*2 cube root ( 2x ) - 2*4 cube root ( 2x )

8 cube root ( 2x ) - 8cube root ( 2x ) = 0

final answer = 0
