EDIT:
-7x - (-4x^3) when x = 4
substitute 4 in x
-7*4 - (-4*4^3)
= -28 -(-4*64)
= -28 - (-256)
= -28 + 256
= 228

-7(4)-(-4(4^3)) would be -28-(-4(64)) which is -28-(-256) which is -28+256 which is 228. im pretty sure im right....if not someone correct me!

i believe click here is right, from the look of his work
he is right for the simple fact if u look the parenthesis are around the whole thing so u apply the cubed root to the whole parenthesis not just the x (which u replaced with 4)
