B³=24•(-1,5)³–¹=24•2,25

To evaluate the expression \( B^3 = 24 \cdot (-1.5)^3 - 1 = 24 \cdot 2.25 \), let's break it down step by step. 1. **Calculate \((-1.5)^3\)**: \[ (-1.5)^3 = -1.5 \cdot -1.5 \cdot -1.5 = -3.375 \] 2. **Rewrite the expression**: Now substituting \((-1.5)^3\) into the equation: \[ B^3 = 24 \cdot (-3.375) - 1 \] 3. **Calculate \(24 \cdot (-3.375)\)**: \[ 24 \cdot (-3.375) = -81 \] 4. **Substitute back**: Now substituting this value back into the equation: \[ B^3 = -81 - 1 = -82 \] Thus, \[ B^3 = -82 \] If you need to find \(B\), take the cube root of \(-82\): \[ B = \sqrt[3]{-82} \] At this stage, if a numerical approximation is required, you can use a calculator: \[ B \approx -4.326 \] So finalize the answers as: - \(B^3 = -82\) - \(B \approx -4.326\)
