Ответ:
- \(\sqrt{81\cdot16}=\sqrt{81}\cdot\sqrt{16}=9\cdot4=36\).
- \(\sqrt{0.09\cdot25}=\sqrt{2.25}=1.5\).
- \(\sqrt{0.01\cdot0.04\cdot121}=\sqrt{0.0484}=0.22\).
- \(30\frac{1}{4}=\frac{121}{4}\), поэтому \(\sqrt{\frac{121}{4}\cdot\frac{49}{36}}=\frac{11}{2}\cdot\frac{7}{6}=\frac{77}{12}\).
- \(\sqrt{6^4\cdot4^2}=\sqrt{(6^2)^2\cdot4^2}=6^2\cdot4=144\).
- \(\sqrt{(-2)^6\cdot0.3^4\cdot(-4)^2}=\sqrt{2^6\cdot(0.3^2)^2\cdot4^2}=8\cdot0.09\cdot4=2.88\).
Ответ: 1) 36; 2) 1,5; 3) 0,22; 4) \(\frac{77}{12}\); 5) 144; 6) 2,88.
