Answer 1

Explicație pas cu pas:

$1,(4) \sqrt{75} \cdot ( - 2.4 \sqrt{50}) \cdot \bigg( - \dfrac{1}{26} \sqrt{18} \bigg) =$

$= \dfrac{14 - 1}{9} \cdot 5\sqrt{3} \cdot \bigg(- \dfrac{24 \cdot 5\sqrt{2} ^{(10} }{10} \bigg) \cdot \bigg( - \dfrac{3 \sqrt{2} }{26}\bigg)$

$= \dfrac{13 \cdot 5 \sqrt{3}}{9} \cdot 12\sqrt{2} \cdot \dfrac{3 \sqrt{2} }{26} = \dfrac{13 \cdot 5 \sqrt{3} \cdot {2}^{2} \cdot 3 \sqrt{2} \cdot 3 \sqrt{2}}{9 \cdot 26}$

$= \dfrac{13 \cdot 5 \sqrt{3} \cdot {2}^{3} \cdot {3}^{2} }{2 \cdot {3}^{2} \cdot 13} = 5 \sqrt{3} \cdot {2}^{2} = 20 \sqrt{3}$
