Ответ:
- \(\sqrt{81\cdot16}=\sqrt{81}\cdot\sqrt{16}=9\cdot4=36\).
- \(\sqrt{0.09\cdot25}=0.3\cdot5=1.5\).
- \(\sqrt{0.01\cdot0.04\cdot121}=0.1\cdot0.2\cdot11=0.22\).
- \(30\frac14=\frac{121}{4}\), поэтому \(\sqrt{\frac{121}{4}\cdot\frac{49}{36}}=\frac{11}{2}\cdot\frac{7}{6}=\frac{77}{12}\).
- \(\sqrt{6^4\cdot4^2}=\sqrt{6^4}\cdot\sqrt{4^2}=36\cdot4=144\).
- \(\sqrt{(-2)^6\cdot0.3^4\cdot(-4)^2}=2^3\cdot0.3^2\cdot4=8\cdot0.09\cdot4=2.88\).
Ответ: 1) 36; 2) 1,5; 3) 0,22; 4) \(\frac{77}{12}\); 5) 144; 6) 2,88.
