Răspuns :

Poti face in 2 metode:
Metoda I:
(1+0,5)(1-0,5)+1/2=
1^2-(0,5)^2+0,5=
1-0,25+0,5=
0,75+0,5=
1,25

Metoda II:
(1+0,5)(1-0,5)+1/2=
1,5×0,5+0,5=
0,75+0,5=
1,25
Albatran
(1²-0,5²)+0,5=
(1-0,25)+0,5
0,75+0,5=
1,25
AS SIMPLE AS THAT!


A LTFEL
1,5*0,5+0,5= 0,5(1.5+1)=0,5*2,5=1,25
AS SIMPLE AS THAT!
