(-125)*(-25)*(-5)*2*(-4)*(-8) =要简便算式
(-125)*(-25)*(-5)*2*(-4)*(-8) =要简便算式
-125X-8x-25x-4x-5x2=1000x100x-10
=（-125)*（-8）*（-5）*（-4)*2
=1000*20*2
=40000
(-125)x(-25)x(-5)x2x(-4)x(-8)
=[-125x(-8)]x[-25x(-4)]x[-5x2]
=1000x100x(-10)
=-1000000
(-125)*(-25)*(-5)*2*(-4)*(-8)
=-(125*8)*(25*4)*(5*2)
=-10^6
=-1000000

125*3-125*5+25*25
-84×125+125×67+5×25
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
125减25除5乘2如何等于40
