Answer 1

Răspuns:

sper sa fie bine!

Explicație pas cu pas:

X=1/2;-2/5;4/9;-7/10;0,3;-1,2;0,(4);1,(6);-0/1(6)

X=1/4;4/25;16/81;-42/100;0,9;-2,4;0,(8);2,(12);-0,36

Answer 2

x=1/2
x^2=(1/2)^2=1/4

x=-2/5
x^2=(-2/5)^2=4/25

x=4/9
x^2=(4/9)^2=16/81

x=-7/10
x=(-7/10)^2=49/100=0,49

x=0,3
x^2=(0,3)^2=0,09

x=-1,2
x^2=(-1,2)^2=1,44

x=0,(4)
x^2=[0,(4)]^2=(4/9)^2=16/81

x=1,(6)
x^2=[1,(6)]^2=(15/9)^2=225/81

x=-0,1(6)
x^2=[-0,1(6)]^2=(-15/90)^2=(-1/6)^2=1/36
