To simplify the expression \( y^{-9} \cdot y^{-3} \), we can use the rule of exponents that states \( a^m \cdot a^n = a^{m+n} \).
Applying this rule, we have:
\[
y^{-9} \cdot y^{-3} = y^{-9 + (-3)} = y^{-12}
\]
Next, we want to express our answer in exponential form with positive exponents. To do this, we can rewrite \( y^{-12} \) as:
\[
y^{-12} = \frac{1}{y^{12}}
\]
Thus, the fully simplified expression in exponential form with positive exponents only is:
\[
\frac{1}{y^{12}}
\]
