$1)quad (2sqrt5)^2=4cdot 5=20; ,; (sqrt3)^4=3^2=9; ,; (sqrt5)^2=5; ,; \\(-3sqrt2)^2=9cdot 2=18\\(sqrt5)^2 textless (sqrt3)^4 textless (-3sqrt2)^2 textless (2sqrt5)^2\\2)quad (-sqrt7)^2=7; ,; -(-sqrt6)^2=-6; ,; (-2sqrt2)^2=4cdot 2=8; ,\\(sqrt{0,5})^4=0,5^2=0,25\\-(-sqrt6)^2 textless (sqrt{0,5})^4 textless (-sqrt7)^2 textless (-2sqrt2)^2\\3)quad -4sqrt{2^2}=-4cdot 2=-8; ,; (4sqrt2)^2=16cdot 2=32; ,\\-(2sqrt3)^2=-4cdot 3=-12; ,; -sqrt{11^2}=-11\\-(2sqrt3)^2 textless -sqrt{11^2} textless -4sqrt{2^2} textless (4sqrt2)^2$

$4)quad (sqrt8)^2=8; ,; sqrt{(-5)^2}=sqrt{25}=5; ,\\ (-(-sqrt3)^2)^2=+(-sqrt3)^4=(sqrt3)^4=3^2=9; ,\\-(-sqrt2)^6=-(sqrt2)^6=-2^3=-8\\-(-sqrt2)^6 textless sqrt{(-5)^2} textless (sqrt8)^2 textless (-(-sqrt3)^2)^2$
