Question

Quanto é:
$50 \times 120 \sqrt{2} - 5 \times \frac{480}{14}$
​

Answer 1

Fatorando;

$50 \times 120 \sqrt{2} - 5 \times \frac{480}{14} \\ 6000 \sqrt{2} - 5 \frac{480}{14} \\ 5(1200 \sqrt{2} - \frac{480}{14} </em></strong><strong><em>)</em></strong><strong><em>\\ 5(1200 \sqrt{2} - \frac{240}{7} )$

Simplificando;

$6000 \sqrt{2} - 5 \times \frac{240}{7} = 6000 \sqrt{2} - \frac{1200}{7}$
