Simplify: `(-3)^(2)xx10^4`

Answer

To simplify the expression \((-3)^{2} \times 10^{4}\), we will follow these steps:

### Step 1: Calculate \((-3)^{2}\)
The expression \((-3)^{2}\) means \(-3\) multiplied by itself:
\[ (-3) \times (-3) = 9 \]

### Step 2: Calculate \(10^{4}\)
The expression \(10^{4}\) means \(10\) multiplied by itself four times:
\[ 10^{4} = 10 \times 10 \times 10 \times 10 = 10000 \]

### Step 3: Multiply the results from Step 1 and Step 2
Now, we multiply the results from Step 1 and Step 2:
\[ 9 \times 10000 = 90000 \]

### Final Answer
Thus, the simplified expression is:
\[ \boxed{90000} \]
