The expression "three negative power of four" can be interpreted as \( 4^{-3} \).
To solve this using the property of negative integer exponents, we can use the formula:
\[ a^{-n} = \frac{1}{a^n} \]
Applying this to our expression:
\[ 4^{-3} = \frac{1}{4^3} \]
Now, calculate \( 4^3 \):
\[ 4^3 = 4 \times 4 \times 4 = 16 \times 4 = 64 \]
Substituting back, we have:
\[ 4^{-3} = \frac{1}{64} \]
Therefore, the answer is:
\[ \frac{1}{64} \]
