0037x05x06脱式计算

28X7X6脱式计算28X7X6=196*6=1176 直接计算的

5x48x6=240x6=1440

1650-480÷16*15=1650-450=1200 1.3÷0.5÷2.6 =2.6/2.6=1 496+250*16 =496+4000=4496 123+5.67+8.77*567 =5101.26 123+5.67+8.77*567 =123+567*0.01+567*8.77=123+567*(0.01+8.77)=123+4978.26=5101.26

18x5x6=90*6=540

44x25x6=(40+4)x256=(40x25+425)x6=(1000+100)6=11006=6600 再看看别人怎么说的.

63020的脱式计算63020=630÷20=31.5验算、31.5820=630

28=20+8.20=10x2.8=2x2x2..2.2750625x28=.x(10x2+2x2x2)2.2750625x10x2+.x2x2x2=22.750625x2+4.550125x2x2=45.50125+9.10025x2=45.50125+18.2005=63.70175有用请采纳

一个数的计算只能是分解质因数了:30153015=3x5x67x73x137

脱式计算咋写40.5÷0.81x0.18=50*0.18=9

简便计算过程方法如下解:78.21-27.65 +7.99=78.21+7.99-27.65=86.2-27.65=58.55
