The given expression can be simplified by factoring out the common factor in each term. The expression is: $7 \cdot 48 - 9 \cdot 192 - 7 \cdot 147$. Factoring out the common factors, we get:- $7 \cdot 48 = 7 \cdot (3 \cdot 16) = 7 \cdot 3 \cdot 16$- $9 \cdot 192 = 9 \cdot (3 \cdot 64) = 9 \cdot 3 \cdot 64$- $7 \cdot 147 = 7 \cdot (3 \cdot 49) = 7 \cdot 3 \cdot 49$So, the expression becomes:- $7 \cdot 3 \cdot 16 - 9 \cdot 3 \cdot 64 - 7 \cdot 3 \cdot 49$Factoring out $3$ from each term, we get:- $3(7 \cdot 16 - 9 \cdot 64 - 7 \cdot 49)$Calculating each term:- $7 \cdot 16 = 112$- $9 \cdot 64 = 576$- $7 \cdot 49 = 343$So, the expression is:- $3(112 - 576 - 343)$- $3(-464 - 343)$- $3(-807)$- $-2421$Dividing by 3:- $-2421 / 3 = -807$It seems there was a mistake in the calculation process. Let's correct the approach focusing on the simplification process:Given: $7 \cdot 48 - 9 \cdot 192 - 7 \cdot 147$Each term can be simplified individually, but the correct approach involves simplifying the entire expression directly, considering the arithmetic operations:- $7 \cdot 48 = 336$- $9 \cdot 192 = 1728$- $7 \cdot 147 = 1029$So, the expression simplifies to:- $336 - 1728 - 1029$Calculating the result:- $336 - 1728 - 1029 = -2421$However, the correct simplification process should focus on common factors and properties of numbers to simplify the expression correctly. The mistake in calculation led to an incorrect conclusion. The correct approach involves simplifying the expression based on arithmetic operations and possibly factoring, aiming for a result that matches one of the given options. Given the mistake in the detailed calculation, let's correct the approach:The correct simplification should directly address the arithmetic without unnecessary factoring, leading to a straightforward calculation. The error in the detailed step-by-step calculation indicates a misinterpretation of the original problem. The goal is to directly simplify the given numerical expression accurately.
