Thanks bợn nhìu nhoa

1: =20*(-4)+24(-30)

=-80-720=-800

2: =-13*57+13*32+57*13-57*45

=13*32-57*45=-2149

3: =-12*8*125

=-12*1000=-12000

4: =(-134)(1-51+48)

=(-134)*(-2)=268

5: =(-24)(45-5)=40*(-24)=-960

   (-134)+51×134+(-134)×48

=-1 x 134 + 51 x 134 + 134 x (-48)

= 134 x ( -1 + 51- 48)

= 134 x 2

= 268

(-134)+51×134+(-134)×48

=(-134)(1+-51+48)

=(-134).-2

=-268

1: \(=-24\left(45-5\right)=-24\cdot40=-960\)

2: \(=-134\left(1-51+48\right)=-134\cdot\left(-2\right)=268\)

3: \(=124\left(1-52+47\right)=124\cdot\left(-3\right)=-372\)

-134 + 51 x 134 + (-134) x 48

= [(-132) + (-134)] + 51 x 134 + 48

= 0 + 51 x 134 + 48

= 0 + 6834 + 48

= 0 + 6882

= 6882

sai r bạn

a: =-45*24+120

=-1080+120

=-960

b: =134(-1+51-48)

=134*2

=268

c: =-41*59-41*2+59*41-59*2

=-2(41+59)

=-200

a: \(\left(-134\right)+51\cdot134+\left(-134\right)\cdot48\)

\(=134\left(-1+51-48\right)=134\cdot2=268\)

b: \(124+\left(-52\right)\cdot124+\left(-124\right)\cdot\left(-47\right)\)

\(=124-52\cdot124+124\cdot47\)

\(=124\left(1-52+47\right)=124\cdot\left(-4\right)=-496\)

c: \(-55\cdot78+13\cdot\left(-78\right)-78\cdot\left(-65\right)\)

\(=78\cdot\left(-55\right)-78\cdot13+78\cdot65\)

\(=78\left(-55-13+65\right)=78\cdot\left(-3\right)=-234\)

d: \(45\cdot\left(-24\right)+\left(-10\right)\cdot\left(-12\right)\)

=-1080+120

=-960

a) = 10 . (-4) + 24. 4

    = 10.(-4) + 96

    = 56

Ở dưới mình nhầm nha hihi

= -800
