To simplify the expression \( 59 \cdot 5^{-13} \) using properties of exponents, we can apply the properties as follows:

First, we can express \( 5^9 \) as \( \frac{5^9}{5^{13}} \) using the property that \( a^m \cdot a^n = a^{m+n} \):

\[ 59 \cdot 5^{-13} = \frac{5^9}{1} \cdot \frac{1}{5^{13}} = \frac{5^9}{5^{13}} \]

Now, we can use the property \( \frac{a^m}{a^n} = a^{m-n} \):

\[ \frac{5^9}{5^{13}} = 5^{9-13} = 5^{-4} \]

Since we want an equivalent expression using only positive exponents, we can rewrite \( 5^{-4} \) as:

\[ 5^{-4} = \frac{1}{5^4} \]

Now let's find which of the provided responses matches \( \frac{1}{5^4} \):

  1. \( 595 - 13 \)
  2. \( \frac{5^9}{5^{-13}} \)
  3. \( \frac{1}{5^4} \)
  4. \( \frac{1}{5^{22}} \)
  5. \( 5^4 \)

The correct equivalent expression is:

\(\frac{1}{5^4}\)

Thus, the answer is:

\(\frac{1}{5^4}\)
