Accepted Answer

\(\sqrt{49}+\sqrt{36}=7+6=13\).
\(\sqrt{81}-\sqrt{100}=9-10=-1\).
\(\sqrt{0.01}\cdot\sqrt{25}=0.1\cdot5=0.5\).
\(\sqrt{64}:\sqrt{0.04}=8:0.2=40\).
\(\sqrt{\frac{36}{49}}\cdot\sqrt{\frac{49}{9}}=\frac67\cdot\frac73=2\).
\(\sqrt{\frac{25}{16}}\cdot\sqrt{\frac{64}{100}}=\frac54\cdot\frac25=\frac12\).
\(\sqrt{3\frac6{25}}\cdot\sqrt{2\frac{28}{36}}=\sqrt{\frac{81}{25}}\cdot\sqrt{\frac{100}{36}}=\frac95\cdot\frac53=3\).
\(\sqrt{144}-\sqrt{169}=12-13=-1\).
\(\sqrt{400}\cdot\sqrt{0.16}=20\cdot0.4=8\).
\(\sqrt{900}-\sqrt{625}=30-25=5\).
\(\sqrt{0.25}\cdot\sqrt{0.49}=0.5\cdot0.7=0.35\).
\(\sqrt{2\frac14}\cdot\sqrt{1\frac79}=\sqrt{\frac94}\cdot\sqrt{\frac{16}{9}}=\frac32\cdot\frac43=2\).
\(\sqrt{0.0001}\cdot\sqrt{100}=0.01\cdot10=0.1\).
\(\sqrt{121}:\sqrt{25}=11:5=\frac{11}{5}\).
