This question wants you to simplify this polynomial. By simplifying, it means to multiply this term by itself 3 times, so you will have...
[tex](-4b^{3w}-4)*(-4b^{3w}-4)*(-4b^{3w}-4)[/tex]
Just start off by foiling the first two parenthesis, then multiply what you get by the third parenthesis and combine like terms
