Ответ:
- \(\sqrt{100\cdot49}=\sqrt{100}\cdot\sqrt{49}=10\cdot7=70\).
- \(\sqrt{81\cdot400}=\sqrt{81}\cdot\sqrt{400}=9\cdot20=180\).
- \(\sqrt{64\cdot121}=\sqrt{64}\cdot\sqrt{121}=8\cdot11=88\).
- \(\sqrt{144\cdot0.25}=\sqrt{144}\cdot\sqrt{0.25}=12\cdot0.5=6\).
- \(\sqrt{0.01\cdot169}=\sqrt{0.01}\cdot\sqrt{169}=0.1\cdot13=1.3\).
- \(\sqrt{2.25\cdot0.04}=\sqrt{2.25}\cdot\sqrt{0.04}=1.5\cdot0.2=0.3\).
Ответ: а) 70; б) 180; в) 88; г) 6; д) 1,3; е) 0,3.
