16\left(\frac{1}{2}\right)^3+8\cdot \:\frac{1}{2}-7
You asked:
Evaluate the expression: \(16 {\left( \frac{1}{2} \right)}^{3} + 8 \cdot \frac{1}{2} - 7\)
MathBot Answer:
\[16 {\left( \frac{1}{2} \right)}^{3} + 8 \cdot \frac{1}{2} - 7 = -1\]
\[\begin{aligned}16 {\left( \frac{1}{2} \right)}^{3} + 8 \cdot \frac{1}{2} - 7& = 16 \cdot \left(\frac{1}{2}\right)^{3} + \frac{8}{2} - 7\\& = \frac{16}{8} + \frac{8}{2} - 7\\& = 2 + \frac{8}{2} - 7\\& = 2 + 4 - 7\\& = 6 - 7\\& = -1\end{aligned}\]
