To evaluate \(-4^3\), we first consider the exponentiation of the base before applying the negative sign.
This can be interpreted as:
\[ -4^3 = -(4^3) \]
Now, calculate \(4^3\):
\[ 4^3 = 4 \times 4 \times 4 = 16 \times 4 = 64 \]
Then apply the negative sign:
\[ -4^3 = -64 \]
So, the final result is:
\[ \boxed{-64} \]
