Let's solve the given expression step by step.

The expression provided is:

\[
\frac{3^{-2}}{3^{-3} \cdot 3^0}
\]

### Step 1: Simplify the denominator
We have the product of two powers of 3 in the denominator:

\[
3^{-3} \cdot 3^0
\]

Using the property of exponents \(a^m \cdot a^n = a^{m+n}\), we combine the powers of 3:

\[
3^{-3} \cdot 3^0 = 3^{-3+0} = 3^{-3}
\]

### Step 2: Rewrite the expression
Now the entire expression becomes:

\[
\frac{3^{-2}}{3^{-3}}
\]

### Step 3: Use the quotient of powers property
Using the property \(\frac{a^m}{a^n} = a^{m-n}\), we simplify the expression:

\[
\frac{3^{-2}}{3^{-3}} = 3^{-2 - (-3)} = 3^{-2 + 3} = 3^1
\]

### Step 4: Final result
The expression simplifies to:

\[
3^1 = 3
\]

Thus, the equivalent expression is **3**.

1. What is the general rule for multiplying powers with the same base?
2. How would the result change if the exponents were positive instead of negative?
3. Can you explain why \(3^0 = 1\) and how it affects the denominator?
4. How would the result be affected if a different base were used?
5. How can the properties of exponents help in solving more complex expressions?

**Tip:** Always simplify powers using the exponent rules before applying other operations, as it makes complex expressions easier to handle.
