Question

Verifica egalitatile:[982-27×(285:5-2×25)-38:2]×2=782:2×5+178 3×[894:3-159:(372-123×3)]=214×3-156:2. Va rog ajutti- ma

Answer 1

[982-27x(285:5-2x25)-38:2]x2=782:2x5+178
[982-27x(57-50)-19]x2=391x5+178
(982-27x7-19)x2=1955+178
(982-189-19)x2=2133
774x2=2133
1548=2133 fals

3x[894:3-159:(372-123x3)]=214x3-156:2
3x[298-159:(372-369)]=642-78
3x(298-159:3)=564
3x(298-53)=564
3x245=564
735=564 fals
