Помогите плииз даю 50 баллов срочно надооо((

Answer 1

$0,2 sqrt{200}= sqrt{0,04*200}= sqrt{8} \ 10 sqrt{3}= sqrt{100*3} = sqrt{300} \ sqrt{8} textless sqrt{300} \ \ 2.5 sqrt{63}= sqrt{6.25*63}= sqrt{393.75} \ 4.5 sqrt{28}= sqrt{20.25*28}= sqrt{567} \ sqrt{393.75} textless sqrt{567} \ \ 0.5 sqrt{108}= sqrt{0.25*108}= sqrt{27} \ 9 sqrt{3}= sqrt{81*3}= sqrt{243} \ sqrt{27} textless sqrt{243}$

Answer 2

1)0,2√200=√(0,04*200)=√8
10√3=√(100*3)=√300
√√8<√300⇒0,2√200<10√3
2)0,5√108=0,5*6√3=3√3
3√3<9√3⇒0,5√108<9√3
3)2,5√63=2,5*3√7=7,5√7
4,5√28=4,5*2√7=9√7
7,5√7<9√7⇒2,5√63<4,5√28
