Question

Вопрос:

Accepted Answer

\(\sqrt{144}-\sqrt{169}=12-13=-1\).
\(\sqrt{400}\cdot\sqrt{0.16}=20\cdot0.4=8\).
\(\sqrt{900}-\sqrt{625}=30-25=5\).
\(\sqrt{0.25}\cdot\sqrt{0.49}=0.5\cdot0.7=0.35\).
\(\sqrt{2\frac{1}{4}}\cdot\sqrt{1\frac{7}{9}}=\frac{3}{2}\cdot\frac{4}{3}=2\).
\(\sqrt{0.0001}\cdot\sqrt{100}=0.01\cdot10=0.1\).
\(\sqrt{121}:\sqrt{25}=11:5=\frac{11}{5}\).
\(\sqrt{0.04}\cdot\sqrt{0.09}=0.2\cdot0.3=0.06\).
\(\sqrt{169}-\sqrt{625}=13-25=-12\).

Ответ: −1; 8; 5; 0,35; 2; 0,1; 11/5; 0,06; −12.
