Question

simplifique a expressão


C= 1/10√50 - 1/6√18

Answer 1

Resposta:

$\frac{1}{10} \sqrt{50} - \frac{1}{6} \sqrt{18} \\ = \frac{1}{10} \sqrt{2. {5}^{2} } - \frac{1}{6} \sqrt{2. {3}^{2} } \\ \frac{1}{10} .5 \sqrt{2} - \frac{1}{6} .3 \sqrt{2} \\ = \frac{5}{10} \sqrt{2} - \frac{3}{6} \sqrt{2} \\ = ( \frac{5}{10(3)} - \frac{3}{6(5)} ) \sqrt{2} \\ = ( \frac{15}{30} - \frac{15}{30} ) \sqrt{2} \\ = \frac{0}{30} \sqrt{2} \\ = 0 \sqrt{2} \\ = 0$
