Question

calcular y luego hallar las raíces ​

Answer 1

$\sqrt{\frac{9}{16} + 1} = \sqrt{\frac{16+9}{16} } = \sqrt{\frac{25}{16} } = \frac{5}{4}$

━━━━━━━━━━━━

$\sqrt{\frac{3}{8} + 3} = \sqrt{\frac{24+3}{8} } = \sqrt{\frac{27}{8} } = \frac{3\sqrt{6} }{4}$

━━━━━━━━━━━━

$\sqrt{\frac{5}{6} + \frac{19}{36} } = \sqrt{\frac{30+19}{36} } = \sqrt{\frac{49}{36} } = \frac{7}{6}$
