Answer:

\frac{1}{27}

Step-by-step explanation:

3^2 ⋅ 3^−5

3^2 \cdot 3^{-5}

To multiply the exponents we apply exponential property

a^m \cdot a^n = a^{m+n}

When we multiply the exponents with same base then we add the exponents

3^2 \cdot 3^{-5}, both terms has same base . so we add the exponents.

3^2 \cdot 3^{-5}=3^{2-5}= 3^{-3}

Now we make the exponent positive

a^{-m}= \frac{1}{a^m}

3^{-3}= \frac{1}{3^3}=\frac{1}{27}
