34 x 1 125 -25 x 34- 34 x 100

= 38 250 - 850 - 34 000

= 37 400 - 34 000

= 3 000

cần làm ra cụ thể ko

a)\(\text{ (-34) + (-91) + (-26) + (-99)}\\ =\left[\left(-34\right)+(-26)\right]+\left[(-91)+(-99)\right]\\ =-60+\left(-190\right)\\ =-250\)

Ý là sao ???????????????????????????????????????????????????

a) (-4)(125)(-25)(-6)(-8)

=[(-4)(-25)].[125.(-8)].(-6)

= 100 . (-1000) . (-6)

= -100000.(-6)=600000

b)(-2)(-2)(-2)(-3)(-3)(-3)

= (-2)³.(-3)³

= [(-2)(-3)]³ = 6³ = 216 

a) (-4).125.(-25).(-6).(-8)

=[(-4).(-25)].[-8.125].-6

=100.-1000.-6

=600000

b)=6³=216

100+125+122+226+78=685

(100+125+(122+78)+(34+226) = 225 + 200 + 260 = 685

100 +125 +122 + 34 +226 +78 = 685

Đáp án B

34 × 2 + 125

= 68 + 125

= 193

\(34000:\left(125.8\right)=34\)

34 000 : 125 : 8
= 34

=272:8

=34
