The Zero Power Rule of Integer Exponents states that any non-zero number raised to the power of zero equals 1.
In your expression \(-4^0 \cdot 15\), we first evaluate \(-4^0\):
\[ -4^0 = 1 \]
Now, substituting this back into the expression gives us:
\[ 1 \cdot 15 = 15 \]
Therefore, the result of \(-4^0 \cdot 15\) is:
\[ \boxed{15} \]
