Question

Помогите решить номера 56,57,58

Answer 1

№ 56
$\frac{ \sqrt{3} }{ \sqrt{27} } = \sqrt{ \frac{3}{27} }= \sqrt{ \frac{1}{9} } = \frac{1}{3}$
$\sqrt{ \frac{3}{2}}= \sqrt{ \frac{3}{2}}* \sqrt{ \frac{2}{2}}= \frac{ \sqrt{6} }{2}= \frac{2,449}{2}=1,225$

№ 57.
$\sqrt{ \frac{2}{3}}=[tex] \sqrt{\frac{2}{3}} * \sqrt{\frac{3}{3}} = \frac{ \sqrt{6} }{3}= \frac{2,449}{3}=0,8163$
$\sqrt{\frac{3}{2}}= \sqrt{\frac{6}{4}} = \frac{2,449}{4}=1,6122$
$\sqrt{\frac{3}{8}}= \sqrt{\frac{6}{16}}= \frac{2,449}{16}=0,1530$
$\sqrt{ \frac{3}{32}}= \sqrt{\frac{6}{64}}= \frac{2,449}{64}=0,0382$

№ 58.
$\sqrt{5}* \sqrt{2}* \sqrt{10}= \sqrt{5*2*10}= \sqrt{100}=10$
$\sqrt{14}* \sqrt{2}* \sqrt{28}= \sqrt{14*2*28}= \sqrt{784}=28$
$\sqrt{10}* \sqrt{5}* \sqrt{32}= \sqrt{10*5*32}= \sqrt{1600}=40$
$\sqrt{\frac{2}{11}}*\sqrt{\frac{3}{11}}*\sqrt{\frac{2}{27}}= \sqrt{x} \sqrt{\frac{2}{11}* \frac{3}{11} *\frac{2}{27}}=\sqrt{\frac{4}{1089}}= \frac{2}{33}$
$\sqrt{ \frac{13}{15}}* \sqrt{ \frac{2}{5}}* \sqrt{ \frac{26}{3}}= \sqrt{ \frac{26*26}{15*15}}= \frac{26}{15}=1 \frac{11}{15}$
$\sqrt{7}* \sqrt{ \frac{32}{35}}* \sqrt{ \frac{2}{5}}= \sqrt{ \frac{7*32*2}{35*5}}= \sqrt{ \frac{64}{25}}= \frac{8}{5}=1 \frac{3}{5}$
