Respuesta:

(−2) 3 − 15 ÷ (−3) + √4 3 . √2 3 . √2 3

$\frac{\left(-2\right)\cdot \:3-15}{\left(-3\right)+\sqrt{4}\cdot \:3\sqrt{2}\cdot \:3\sqrt{2}\cdot \:3}\\\\\\=\frac{-2\cdot \:3-15}{-3+\sqrt{4}\cdot \:3\sqrt{2}\cdot \:3\sqrt{2}\cdot \:3}\\\\\\=\frac{-21}{-3+3\cdot \:3\cdot \:3\sqrt{4}\sqrt{2}\sqrt{2}}\\\\\\=\frac{-21}{-3+3\cdot \:3\cdot \:3\sqrt{4}\sqrt{2}\sqrt{2}}\\\\\\=\frac{-21}{-3+54\sqrt{4}}\\\\\\=-\frac{21}{-3+54\sqrt{4}}\\\\\\=-\frac{1}{5}$
