To simplify the equation \(81 - \frac{54}{3^2}\), we first calculate \(3^2\):
\[
3^2 = 9
\]
Next, we divide \(54\) by \(9\):
\[
\frac{54}{9} = 6
\]
Now, we substitute back into the equation:
\[
81 - 6
\]
Finally, we perform the subtraction:
\[
81 - 6 = 75
\]
So, the simplified equation evaluates to \(75\), not \(3\). Therefore, Scott's simplification is incorrect. The correct answer is \(75\).
