Question

Tính :

a) \(\left(-4\right).\left(-5\right).\left(-6\right)\)

b) \(\left(-3+6\right).\left(-4\right)\)

c) \(\left(-3-5\right)\left(-3+5\right)\)

d) \(\left(-5-13\right):\left(-6\right)\)

Answer 1

a.-120

b. - 12

c. - 16

d. 3

Answer 2

a) (−4).(−5).(−6)= 20.(-6)= -120

b) (−3+6).(−4)= 3.(-4)= -12

c) (−3−5)(−3+5)= -8. 2 = -16

d) (−5−13):(−6)= -18:( -6)= 3

Answer 3

a,(-4).(-5).(-6)=(-120)

b,

c,

d,

Answer 4

a)(-4).(-5).(-6)=-(4.5.6)=-120

b)(-3+6).(-4)=3.(-4)=-12

c)(-3-5).(-3+5)=(-8).2=-16

d)(-5-14):(-6)=(-19):(-6)=3,1(6)có thể lm tròn=3
