Answer 1

Răspuns:

a)=19\/2

____

5

4\/-4\/2+5\/2-2•(3\/2÷5)

5\/2•3\/2

___

5

5\/2-6\/2

___

5

b)=1-5\/3

1-3\/3+4\/3+6\/3+3(\/3-5\/32)

1-3\/3+4\/3+6\/3+3•(-4\/3)

1-3\/3+4\/3+6\/3-12\/3

c)=11\/5

2(5\/5-\/5)-3\/5+6\/5

2•4\/5-3\/5+6\/5

8\/5-3\/5+6\/5

d)=2-305\/3

2-(30\/3+17•3²\/3)-42\/3-80-\/3

2-(30\/3+17•9\/3)-42\/3-80-\/3

2-(30\/3+153\/3)-42\/3-80-\/3

2-183\/3-42\/-80-\/3

e)3\/10-12\/3(-\/30+4\/3+\/2)

2(13\/10-48-4\/6)

26\/10-96-8\/6

2(13\/10-48-4\/6)

26\/10-96-8\/6

sper ca măcar cele înainte de ultimul is bune noroc:)♡
