(32+16)x20用简便怎么算

原式=960x(50x3-2x3) =960x144 =1000x144-40x144 =144000-5760 =138240

32×(230-192÷16) =32x(230-12) =32x218 =6976

76-(32+16)用简便方法计算 =76-16-32 =60-32 =28

32X16+14X32 =32X(16+14) =32X30 =960

32*16+14*32 =32*(16+14) =32*30 =960 亲,请【采纳答案】,您的采纳是我答题的动力,谢谢。

16×98+32 =16×92+16×2 =16×(98+2) =16×100 =1600

假设:s=1/2+1/4+1/8+1/16+1/32+1/64 ;则:2s=1+1/2+1/4+1/16+1/32 ;用2s-s(相同项全部抵消,只剩首位2项) ;s=1-1/64=63/64。 1.分式加减法法则:(1)通分:把异分母的分式化为同分母分式的过程,叫做通分。 (2)同分母分式的加减法法则:...

(4+16+32)×25应该怎么简便计算 =4x25+4x(4x25)+8x(4x25) =100+400+800 =1300

(16+32+36+40)÷4 =16÷4+32÷4+36÷4+40÷4 =4+8+9+10 =12+19 =31 谢谢,请采纳

(1-1/2-1/4-1/8-1/16-1/32)×64 =64-32-16-8-4-2 =64-(32+16+8+4+2) =64-((32+8)+(16+4)+2) =64-(40+20+2) =64-62 =2
