Ответ:
- При \(x=6, y=2\):
\[\sqrt{\frac{36x^2}{y^4}}=\frac{6|x|}{y^2}=\frac{6\cdot6}{2^2}=\frac{36}{4}=9.\] - При \(x=10, y=5\):
\[\sqrt{\frac{25x^4}{y^6}}=\frac{5x^2}{|y|^3}=\frac{5\cdot100}{125}=4.\] - При \(x=3, y=5\):
\[\sqrt{\frac1{25}x^8y^2}=\frac{x^4|y|}{5}=\frac{81\cdot5}{5}=81.\] - При \(x=7, y=3\):
\[\sqrt{\frac1{9}x^2y^6}=\frac{|x|\,|y|^3}{3}=\frac{7\cdot27}{3}=63.\]
Ответ: 1) 9; 2) 4; 3) 81; 4) 63.
