Simplify: \(9^2 + \sqrt{4^2} - 7\sqrt{16} - 7\).
50
Evaluate each term separately using the order of operations.
\(9^2 = 81\).
\(\sqrt{4^2} = \sqrt{16} = 4\).
\(7\sqrt{16} = 7 \times 4 = 28\).
Now substitute back: \(81 + 4 - 28 - 7\).
\(81 + 4 = 85\), then \(85 - 28 = 57\), then \(57 - 7 = 50\).
Hence, the simplified value of the expression is 50.
