Ответ:
- а)
\(\sqrt{0{,}01\cdot36\cdot64}=\sqrt{23{,}04}=4{,}8\).
- б)
\(\sqrt{0{,}49\cdot25\cdot9}=\sqrt{110{,}25}=10{,}5\).
- в)
\(\sqrt{1690\cdot490}=\sqrt{169\cdot49\cdot100}=13\cdot7\cdot10=910\).
- г)
\(\sqrt{0{,}16\cdot8\cdot50}=\sqrt{64}=8\).
- д)
\(\sqrt{13}\cdot\sqrt{52}=\sqrt{13\cdot52}=\sqrt{676}=26\).
- е)
\(\sqrt{27}\cdot\sqrt{3}=\sqrt{81}=9\).
- ж)
\(\sqrt{\frac{49}{100}}=\frac{7}{10}=0{,}7\).
- з)
\(\sqrt{\frac{256}{25\cdot100}}=\frac{16}{50}=\frac{8}{25}=0{,}32\).
- и)
\(\frac{\sqrt{15}}{\sqrt{735}}=\sqrt{\frac{15}{735}}=\sqrt{\frac{1}{49}}=\frac{1}{7}\).
- к)
\(\frac{\sqrt{5}}{\sqrt{3\cdot\sqrt{15}}}=\sqrt{\frac{5}{3\sqrt{15}}}=\sqrt{\frac{\sqrt{15}}{9}}=\frac{\sqrt[4]{15}}{3}\).
