2*2³ + 3*2+4²
You asked:
Evaluate the expression: \(2 \cdot {2}^{3} + 3 \cdot 2 + {4}^{2}\)
MathBot Answer:
\[2 \cdot {2}^{3} + 3 \cdot 2 + {4}^{2} = 38\]
\[\begin{aligned}2 \cdot {2}^{3} + 3 \cdot 2 + {4}^{2}& = 2 \cdot 2^{3} + 3 \cdot 2 + 4^{2}\\& = 2 \cdot 8 + 3 \cdot 2 + 4^{2}\\& = 16 + 3 \cdot 2 + 4^{2}\\& = 16 + 6 + 4^{2}\\& = 16 + 6 + 16\\& = 22 + 16\\& = 38\end{aligned}\]
