To simplify the expression \( 37 \cdot 3^{-9} \) using the Properties of Integer Exponents, we can rewrite \( 3^{-9} \) as \( \frac{1}{3^9} \). This gives us:
\[ 37 \cdot 3^{-9} = 37 \cdot \frac{1}{3^9} \]
Next, we can rewrite this as:
\[ \frac{37}{3^9} \]
Now, we need to compute \( 3^9 \):
\[ 3^9 = 19683 \]
So, we can rewrite the expression as:
\[ \frac{37}{19683} \]
Thus, the final answer to the expression, simplified as a fraction with no remaining exponents, is:
\[ \frac{37}{19683} \]
