64×0.125×0.5×0.25=(8×4×2)×0.125×0.5×0.25=(8×0.125)×(2×0.5)×(4×0.25)=1×1×1=1
(6.9x0.125x1.75)÷(2.3x1/8x1/4)=(6.9x1/8x7/4)÷(2.3x1/8x1/4)=(6.9÷2.3)x(1/8÷1/8)x(7/4÷1/4)=3x1x7=21
1÷1+0×54.98×1=1+0=193×0.125×11-93×10.025×3=93×1.375-93×30.375=93×(1.375-30.375)=93×(-29)=-2697
0.125x8x4x25再答:等于1x100
0.125*8*0.25*4,答案为1
0.25×3.2×0.125=0.25×4×0.8×0.125=﹙0.25×4﹚×﹙0.8×0.125﹚=1×0.1=0.1
你可别被楼上蒙了=(2.5×0.2)×(8×0.125)=0.5楼上小学没毕业
0.125乘3.2等于0.125乘(8)乘(0.4)
原式=2.3*5.7-2.3*3*1.9=2.3*(5.7-5.7)=0
2*3+5*9行不?
0.125×2.75+0.125×4.25+12.5%=0.125×2.75+0.125×4.25+0.125=0.125×(2.75+4.25+1)=0.125×8=1
0.125x0.25x0.5x(8x0.4x0.2)=(0.125x8)x(0.25x0.4)x(0.5x0.2)=1x0.1x0.1=0.01
0.5*0.25*0.125*64=0.5*2*0.25*4*0.125*8=1*1*1=1
(6.9*0.25*1.75)=6.9*(1/4)*(7/4)(6.9*0.25*1.75)/[2.3*(1/8)*(1/4)]=[6.9*(1/4)*(7/4)]/[2.3*(1/8)*(1/4)]
(1×2.3×4.5+3×6.9×13.5)分之(2×4.6×9+4×9.2×18)=1×2.3×4.5×(1+3×3×3)分之【1×2.3×4.5×(2×2×2+4×4×4)】=(1+3×3×3)分
10再问:我要过程!再答:我给你说简便方法再答:你先采纳再答:0.125×8等于1再问:过程呢?再答:前面就等于3.14再算后面再答:后面等于6.86再答:6.86+3.14就等于10再答:6.86+
简便计算求解答5.5乘4.4-4.4乘3.3-4.4乘2.2=(5.5-3.3-2.2)×4.4=0×4.4=00.00695乘2500+69.5乘0.24+5.1乘6.95=6.95×2.5+6.9
(-0.125)乘(-0.6)乘(-8)乘一又三分之2乘(-5)=0.125*8*3/5*5/3*5=519又5分之4乘(-10)=(19+4/5)*(-10)=-19+8=-1113分之7乘(-9)
解题思路:考查幂的运算解题过程:解:(1)第一次撕成2片,即21;第二次撕成4片,即22;....所以第n次撕成2n,则2n=64所以n=6所以要把这张纸撕成64片需要6次(2)撕7次后这张纸变成27
