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