Question

A si b dupa modelul asta dau coroană urgent va rog ​

Answer 1

a)

$7=\sqrt{49} \\2\sqrt{11} =\sqrt{44} \\4\sqrt{3}=\sqrt{48} \\3\sqrt{5} =\sqrt{45} \\\sqrt{49} >\sqrt{48} >\sqrt{45} >\sqrt{44} \\\\=> 7;4\sqrt{3} ;3\sqrt{5} ;2\sqrt{11}$

b)

$8=\sqrt{64} \\3\sqrt{7} =\sqrt{63} \\6\sqrt{2}=\sqrt{72} \\2\sqrt{15} =\sqrt{60} \\\sqrt{72} >\sqrt{64} >\sqrt{63} >\sqrt{60} \\\\=>-\sqrt{72} <-\sqrt{64} <-\sqrt{63} <-\sqrt{60}\\\\=>-2\sqrt{15};-3\sqrt{7};-8;-6\sqrt{2}$

Succes la scoala!
