If A # B = A² + B, A @ B = A - B, A * B = A + 2B, then what is the value of: 5 # 3 @ 2 * 4?
34
34 is correct.
The three symbols are defined as: A # B = \(A^2 + B\), A @ B = \(A - B\), A * B = \(A + 2B\). The expression 5 # 3 @ 2 * 4 is evaluated step by step from left to right.
Step 1: 5 # 3 = \(5^2 + 3 = 25 + 3 = 28\).
Step 2: 28 @ 2 = \(28 - 2 = 26\).
Step 3: 26 * 4 = \(26 + 2 \times 4 = 26 + 8 = 34\).
Hence, the value of the expression is 34.
