42*3+12^2-8/5
You asked:
Evaluate the expression: \(42 \cdot 3 + {12}^{2} - \frac{8}{5}\)
MathBot Answer:
\[42 \cdot 3 + {12}^{2} - \frac{8}{5} = \frac{1342}{5} = 268.4\]
\[\begin{aligned}42 \cdot 3 + {12}^{2} - \frac{8}{5}& = 42 \cdot 3 + 12^{2} - \frac{8}{5}\\& = 126 + 12^{2} - \frac{8}{5}\\& = 126 + 144 - \frac{8}{5}\\& = 270 - \frac{8}{5}\\& = \frac{1342}{5}\end{aligned}\]
