To convert the expression \( \frac{3^{-17}}{8^{-14}} \) to one with positive exponents, we apply the property of negative exponents, which states that \( a^{-n} = \frac{1}{a^n} \).
Using this property, we can rewrite the expression:
\[ \frac{3^{-17}}{8^{-14}} = \frac{1}{3^{17}} \cdot 8^{14} \]
This can also be expressed as:
\[ \frac{8^{14}}{3^{17}} \]
Now, we can keep it as \( \frac{8^{14}}{3^{17}} \) which has only positive exponents.
Thus, the final equivalent expression with positive exponents only is:
\[ \frac{8^{14}}{3^{17}} \]
