3*[28-4{12*4รท(4*5-4)}]
You asked:
Evaluate the expression: \(3 \cdot \left(28 - 4 \cdot \frac{12 \cdot 4}{4 \cdot 5 - 4}\right)\)
MathBot Answer:
\[3 \cdot \left(28 - 4 \cdot \frac{12 \cdot 4}{4 \cdot 5 - 4}\right) = 48\]
\[\begin{aligned}3 \cdot \left(28 - 4 \cdot \frac{12 \cdot 4}{4 \cdot 5 - 4}\right)& = 3 \cdot \left(28 - 4 \cdot 12 \cdot 4 \cdot \frac{1}{4 \cdot 5 - 4}\right)\\& = 3 \cdot \left(28 - 4 \cdot 12 \cdot 4 \cdot \frac{1}{20 - 4}\right)\\& = 3 \cdot \left(28 - 4 \cdot 12 \cdot \frac{4}{16}\right)\\& = 3 \cdot \left(28 - 4 \cdot \frac{12}{4}\right)\\& = 3 \cdot \left(28 - \frac{48}{4}\right)\\& = 3 \cdot \left(28 - 12\right)\\& = 3 \cdot 16\\& = 48\end{aligned}\]
