(-88) : (-4)-125 : (-5)la putere2 - 380 =
{6 - [282 * (-1) - (44 : 11 - 18)]} - 644 =
25la putere2 : (-5)la putere2 - {42 + 3 * [6 - (3la putere3 * 5 + 11 )]} =

Answer 1

1. 144: (-12) +7*(-2³) +2010

12+7*16+2010

12+126+2010

138+2010

2148

2. -88: (-4) -125: (-5²)-380

22-125:(-25)-380

22-41-380

-19-380

(-361)

3. {6-[282*(-1) -(44: 11-18)]}-644

{6-[282*(-1) -(4-18)]}-644

{6-[282*(-1) -(-14)]}-644

{6-[282-(-14)]}-644

{6-268}-644

262-644

-382

4. 25²: (-5²)- {42+3*[6-(3³*5+11) ]}

25²: (-5²) -{42+3*[6-(27*16) ]}

25²: (-5²) - {42+3*[6-446]}

25²: (-5²) -{42+3*(-440)]}

25²: (-5²) -{42+1320}

25²: (-5²) -1362

625: 25-1352

25-1352

-1327
