Ответ:
- \(\sqrt{49x^8y^4}=7x^4y^2\). При \(x=2, y=3\): \(7\cdot2^4\cdot3^2=7\cdot16\cdot9=1008\).
- \(\sqrt{9x^4y^6}=3x^2y^3\). При \(x=5, y=3\): \(3\cdot5^2\cdot3^3=3\cdot25\cdot27=2025\).
- \(\sqrt{36x^4y^4}=6x^2y^2\). При \(x=5, y=3\): \(6\cdot5^2\cdot3^2=6\cdot25\cdot9=1350\).
- \(\sqrt{25x^4y^4}=5x^2y^2\). При \(x=3, y=7\): \(5\cdot3^2\cdot7^2=5\cdot9\cdot49=2205\).
- \(\sqrt{16x^4y^6}=4x^2y^3\). При \(x=7, y=2\): \(4\cdot7^2\cdot2^3=4\cdot49\cdot8=1568\).
Ответ: 3.1) 1008; 3.2) 2025; 3.3) 1350; 3.4) 2205; 3.5) 1568.
