Ответ:

  1. \(\sqrt{\frac{36x^2y^6}{y^2}}=6|x|y^2\). При \(x=6,y=9\): \(6\cdot6\cdot9^2=2916\).
  2. \(\sqrt{\frac{25x^2}{y^4}}=\frac{5|x|}{y^2}\). При \(x=10,y=5\): \(\frac{50}{25}=2\).
  3. \(\sqrt{\frac{4x^2}{y^6}}=\frac{2|x|}{|y^3|}\). При \(x=8,y=2\): \(\frac{16}{8}=2\).
  4. \(\sqrt{\frac{16x^4}{y^6}}=\frac{4x^2}{|y^3|}\). При \(x=4,y=2\): \(\frac{64}{8}=8\).
  5. \(\sqrt{\frac{25x^4}{y^6}}=\frac{5x^2}{|y^3|}\). При \(x=10,y=5\): \(\frac{500}{125}=4\).
  6. \(\sqrt{\frac{36x^2}{y^4}}=\frac{6|x|}{y^2}\). При \(x=6,y=2\): \(\frac{36}{4}=9\).
  7. \(\sqrt{\frac{16x^8}{y^6}}=\frac{4x^4}{|y^3|}\). При \(x=2,y=4\): \(\frac{64}{64}=1\).
  8. \(\sqrt{\frac{9x^4}{y^6}}=\frac{3x^2}{|y^3|}\). При \(x=9,y=3\): \(\frac{243}{27}=9\).
