Evaluate: \( 7 \star 3^{2}+7 \star 4 \)

To evaluate the expression \( 7 \star 3^{2}+7 \star 4 \), we first need to clarify the symbol \( \star \). If we treat \( \star \) as multiplication, the expression simplifies as follows: 1. Calculate \( 3^2 \): \[ 3^2 = 9 \] 2. Substitute back into the expression: \[ 7 \star 9 + 7 \star 4 \] 3. Perform the multiplication: \[ 7 \times 9 = 63 \] \[ 7 \times 4 = 28 \] 4. Add the results: \[ 63 + 28 = 91 \] Thus, the value of the expression \( 7 \star 3^{2}+7 \star 4 \) is \( \boxed{91} \).
