You asked:

Evaluate the expression: (27+33−643)⋅22+15\frac{\left(\sqrt{27 + {3}^{3}} - \sqrt[3]{64}\right) \cdot {2}^{2 + 1}}{5}

MathBot Answer:

(27+33−643)⋅22+15=−325+2465≈5.35755076535925487134696355858828\frac{\left(\sqrt{27 + {3}^{3}} - \sqrt[3]{64}\right) \cdot {2}^{2 + 1}}{5} = - \frac{32}{5} + \frac{24 \sqrt{6}}{5} \approx 5.35755076535925487134696355858828

(27+33−643)⋅22+15=(27+33−643)⋅22+1⋅15=(27+27−643)⋅22+1⋅15=(54−643)⋅22+1⋅15=(3⋅6−643)⋅22+1⋅15=(3⋅6−4)⋅22+1⋅15=(−4+3⋅6)⋅22+1⋅15=(−4+3⋅6)⋅23⋅15=(−4+3⋅6)⋅85=−325+245⋅6\begin{aligned}\frac{\left(\sqrt{27 + {3}^{3}} - \sqrt[3]{64}\right) \cdot {2}^{2 + 1}}{5}&=\left(\sqrt{27 + 3^{3}} - \sqrt[3]{64}\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(\sqrt{27 + 27} - \sqrt[3]{64}\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(\sqrt{54} - \sqrt[3]{64}\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(3 \cdot \sqrt{6} - \sqrt[3]{64}\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(3 \cdot \sqrt{6} - 4\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(-4 + 3 \cdot \sqrt{6}\right) \cdot 2^{2 + 1} \cdot \frac{1}{5}\\&=\left(-4 + 3 \cdot \sqrt{6}\right) \cdot 2^{3} \cdot \frac{1}{5}\\&=\left(-4 + 3 \cdot \sqrt{6}\right) \cdot \frac{8}{5}\\&=- \frac{32}{5} + \frac{24}{5} \cdot \sqrt{6}\end{aligned}
