Question

ajutor!! Dau coroana!!

Answer 1

e) mai intai calculez paranteza rotunda

1 si1/6=7/6

7/6-1/2=4/6=2/3

2:2/3=2/1*3/2=3

apoi ce a ramas in paranteza patrata

2^2-3+1/10=1+1/10=11/10

se termina si acolada

2:11/10=2/1*10/11=20/11

2-20/11=2/11

iar la final

2:2/11=2/1*11/2=11

f)

calculam separat cele 2 paranteze rotunde (p1 si p2)

p1=1/2+1/2*1/2=1/2+1/4=3/4

p2 = 2 si 1/3- 2 si 1/7: 1 si 11/14=7/3- (15/7:25/14)=7/3-15/7*14/25=7/3-6/5=17/15

inmultim p2*1/17=17/15*1/17=1/15

1/12:p1=1/12:3/4=1/12*4/3=1/9

La final

1/9+1/15=8/45
