​

Answer 1

Respuesta:

Explicación paso a paso:

$\sqrt{3}+\sqrt{5}=3.9681\\\\b).-\\0.7+18-\frac{4}{3}$

$0.7=\frac{7}{10}\\0.7+18-\frac{4}{3}=\frac{7}{10}+18=\frac{7}{10}+\frac{180}{10}-\frac{4}{3}=\frac{187}{10}-\frac{4}{3}=\frac{(3)(187)-(10)(4)}{(10)(3)}=\frac{561-40}{30}=\\=\frac{521}{30}$

$c).-\\\frac{3}{8}+\sqrt{2}+9.25=\frac{3}{8}+\sqrt{2}+\frac{925}{100}=\\=\frac{3}{8}+\sqrt{2}+\frac{37}{4}=\frac{3}{8}+\frac{74}{8}+\sqrt{2}=\\=\frac{77}{8}+\sqrt{2}=11</p><p>0392$

$d).-\\-23+4,29-\frac{9}{5}=-18.71-\frac{9}{5}=-\frac{1871}{100}-\frac{9}{5}=\\=-\frac{2051}{100}$
