2.(radical 1+3)la 2+(radical 7-3rdical 2)la 2-(radical 15-radical7)(radical15+radical 7
3.(radical -2)la 2+2(1+radical 6)la 2+(radical 6-2)(radical 6+2)
va rog dau coroana

Answer 1

1.(3 radical 5-1)la 2+radical 180-(2 radical 3-radical 5)(2radical3+radical5
(3√5-1)²+√180-(2√3-√5) (2√3+√5)=
[(3√5)²-2x3√5+1²)+6√5-[(2√3)²-√5²]=
9x5-6√5+1+6√5-4x3+5=
45+1-12+5=
46-12+5=39

la 2 si 3 nu inteleg prea bine. Iti recomand sa folosesti simbolurile matematice si exponent si indice
