Ответ:
- \(\sqrt{32}\cdot\sqrt{2}=\sqrt{64}=8\).
- \(\sqrt{45}\cdot\sqrt{5}=\sqrt{225}=15\).
- \(\dfrac{\sqrt{1000}}{\sqrt{160}}=\sqrt{\dfrac{1000}{160}}=\sqrt{\dfrac{25}{4}}=\dfrac{5}{2}\).
- \(\dfrac{\sqrt{108}}{\sqrt{12}}=\sqrt{9}=3\).
- \(\sqrt{13^2-12^2}=\sqrt{169-144}=\sqrt{25}=5\).
Ответ: 8; 15; 5/2; 3; 5.
