Question

5+5x[5+5x (5+5x5–25)]+5: 5 7+[(7-7: 7)x7-(7:7-7: 7)]: 7+777​

Answer 1

Răspuns:

5+5×[5+5×(5+25-25)]+5:5= presupun ca sunt dpua exercitii am inceput prin a calcula din paranteza rotunda

5+5×(5+5×5)+5:5=

5+5×(5+25)+1=

5+5×30+1=

5+5×30+1=

5+150+1=156

ex2

7+[(7-7:7)×7-(7:7-7:7)]:7+777= facem inmultirile si impartirile din paranteza rotunda

7+[(7-1)×7-(1-1)]:7+777= calculam din paranteza rotunda

7+(6×7-0):7+777= am transformat paranteza patrata in rotunda acum o calculam pe aceasta

7+42:7+777= facem impartirea

7+6+777=

13+777=790
