12[20-(-4)² -2]²
You asked:
Evaluate the expression: \(12 {\left( 20 - {\left( -4 \right)}^{2} - 2 \right)}^{2}\)
MathBot Answer:
\[12 {\left( 20 - {\left( -4 \right)}^{2} - 2 \right)}^{2} = 48\]
\[\begin{aligned}12 {\left( 20 - {\left( -4 \right)}^{2} - 2 \right)}^{2}& = 12 \cdot \left(20 - \left(-4\right)^{2} - 2\right)^{2}\\& = 12 \cdot \left(20 - 16 - 2\right)^{2}\\& = 12 \cdot \left(4 - 2\right)^{2}\\& = 12 \cdot 2^{2}\\& = 12 \cdot 4\\& = 48\end{aligned}\]
