Use the product, quotient, and power rules, as necessary, to simplify the following expression. Write the answer with only positive exponents. (4 * 10^-5)^3/(4 * 10^4)^3

To simplify the given expression \((4 \cdot 10^{-5})^3 / (4 \cdot 10^4)^3\) using the product, quotient, and power rules, we'll proceed as follows:

1. **Apply the Power Rule:** \((a \cdot b)^n = a^n \cdot b^n\) to both the numerator and the denominator.

\[
(4 \cdot 10^{-5})^3 = 4^3 \cdot (10^{-5})^3
\]
\[
(4 \cdot 10^4)^3 = 4^3 \cdot (10^4)^3
\]

2. **Calculate the individual components:**

\[
4^3 = 64
\]
\[
(10^{-5})^3 = 10^{-15}
\]
\[
(10^4)^3 = 10^{12}
\]

So, the expression becomes:

\[
\frac{64 \cdot 10^{-15}}{64 \cdot 10^{12}}
\]

3. **Simplify the fraction:**

The \(64\) terms cancel out:

\[
\frac{64 \cdot 10^{-15}}{64 \cdot 10^{12}} = \frac{10^{-15}}{10^{12}}
\]

4. **Apply the Quotient Rule:** \( \frac{a^m}{a^n} = a^{m-n} \)

\[
\frac{10^{-15}}{10^{12}} = 10^{-15 - 12} = 10^{-27}
\]

Thus, the simplified expression is:

\[
10^{-27}
\]

Since the problem requests the answer with only positive exponents, we'll convert the expression as follows:

\[
10^{-27} = \frac{1}{10^{27}}
\]

So, the final answer is:

\[
\frac{1}{10^{27}}
\]
