Let's simplify the equation step by step:
The original equation is:
\[ 81 - \frac{54}{3^2} \]
First, calculate \( 3^2 \):
\[ 3^2 = 9 \]
Next, substitute this back into the equation:
\[ 81 - \frac{54}{9} \]
Now, calculate \( \frac{54}{9} \):
\[ \frac{54}{9} = 6 \]
Now substitute this value back into the equation:
\[ 81 - 6 \]
Finally, perform the subtraction:
\[ 81 - 6 = 75 \]
So, \( 81 - \frac{54}{3^2} = 75 \).
Scott's answer of 3 is incorrect. The correct answer is 75.
