Answer 1

a. (982-27x(57-50)-19)x2=391x5+178

(982-27x7-19)x2=1955+178

(982-189-19)x2=2133

774x2=2133

1548=2133 FALS

b.

3x(298-159:(372-369))=642-78

3x(298-159:3)=564

3x(298-53)=564

3x245=564

735=564 FALS

c.

6048-(4880-(1610-81))-330=2367

6048-(4880-1529)-330=2367

6048-3351-330=2367

2367=2367 ADEVARAT

Answer 2

Răspuns:

[982-27x(57-50)-19]X2=391x5+178

[982-27x7-19]X2= 1955+178

[982-154]X2=2133

828x2=2133

1656nu e egal cu 2133

3x[288-159:(372-369)]=642-78

3x[288-159:3]=564

3x[288-53]=564

3x235=564

705 nu e egal cu 564

6048-[4880-(1610-81]-330=2367

6048-[4880-1529]-330=2367

6048-3351-330=2367

2697-330=2367

2367=2367
