Ответ:

  1. \(\sqrt{18\cdot32}=\sqrt{(2\cdot3)^2\cdot(4\cdot2)^2}=\sqrt{24^2\cdot1^2}=24\). (Так как \(18\cdot32=576=24^2\).)
  2. \(\sqrt{8\cdot98}=\sqrt{784}=28\).
  3. \(\sqrt{3.6\cdot14.4}=\sqrt{51.84}=7.2\).
  4. \(\sqrt{75\cdot48}=\sqrt{3600}=60\).
  5. \(\sqrt{288\cdot50}=\sqrt{14400}=120\).
  6. \(\sqrt{4.5\cdot72}=\sqrt{324}=18\).
  7. \(\sqrt{2.7\cdot1.2}=\sqrt{3.24}=1.8\).
  8. \(\sqrt{80\cdot45}=\sqrt{3600}=60\).
  9. \(\sqrt{33\cdot297}=\sqrt{9801}=99\).
