Let's break down the expression \( 81 - \frac{54}{3^2} \) step by step to see where Scott might have gone wrong.
1. **Calculate \(3^2\):**
\[
3^2 = 9
\]
2. **Calculate \(\frac{54}{3^2}\):**
\[
\frac{54}{9} = 6
\]
3. **Now subtract from 81:**
\[
81 - 6 = 75
\]
So the correct simplification of \( 81 - \frac{54}{3^2} \) is \( 75\), not \( 3\).
Scott's mistake could have been in the division step where he may have miscalculated \( \frac{54}{9} \) or in the overall calculation process.
