4,0.2,0.36,0,108,有什么规律
已知 10m=0.2,10n=4,求:

(1)102m-n(10m)210n=0.01,∵10-2=0.01,∴2m-n=-2;(2)9m÷3n=32m-n=3-2=19.

10根号0.2-2根号0.5+4根号0.125

10根0.2-2根0.5+4根0.125=12根1/5-2根1/2+4根1/8=(12根5)/5-根2+根2=(12根5)/5.

41.20.360.108()()规律:后一个数为前一个乘0.3:41.20.360.108(0.0324)(0.00972)1.6410()()156.25规律:后一个数为前一个除以0.4:1.64

先找出规律,再按规律填数。 (1)4,1.2,0.36,0.108,( ),( ). (2)1.6,4,10,( ),(

解题思路:(1)4×0.3=1.2,1.2×0.3=0.36,0.36×0.3=0.0324,0.0324×0.3=0.00972。连续×0.3(2)连续乘2.5。解题过程:(1)4,1.2,0.36

先找出规律,再填数.(1)4,1.2,0.36,0.108,______,______.(2)1.6,4,10,____

(1)0.108×0.3=0.0324,0.0324×0.3=0.00972;(2)10×2.5=25,25×2.5=62.5;(3)0.375×0.5=0.1875,0.1875×0.5=0.093

0.6:0.36=4/5:X怎么算?0.6:0.36=4/5:X怎么算?

0.36×0.8÷0.6=X0.288÷0.6=XX=0.48这个书上例题有哦而且还不是6下的是6上的吧

0.36×98+3.6×0.2怎么简便计算

3.6X0.2=0.36X2很容易看出来原式可以写成0.36X(98+2)=0.36X100=36

找规律,在填数.(1)4,1.2,0.36,0.108,( ),( ) (2)1.6,4,10,( ),(

依次乘以0.30.03040.00972依次乘以2.52562.5

0.36:X=1/10:4/9 解方程

0.36:X=1/10:4/90.36×4/9=1/10x1/10x=0.16x=1.6

x/25=2.8:4/5.1.2/75=0.7:x.0.36:x=1/10:4/9

4/5X=25x2.8X=87.5再答:1.2X=75x0.7x=43.75再问:还有一个再答:1/10X=0.36x4/9X=1.6再答:送个物品给我嘛?再答:送个物品给我嘛?再问:什么物品再答:1

(1 ) 一个数的2/5比4多0.36,求这个数.(2)24比一个数的20%少0.2,求这个数.

(1)2/5X-4=0.362/5X=4.36X=4.36*5/2X=10.9(2)20%X-0.2=2420%X=24.2X=24.2/20%X=121(3)(X-10)*2+70=250(X-10

(1.25+0.36)0.2的 简便计算?

1.25×0.2+0.36×0.2=0.25+0.072=0.322

0.2分之0.1x+0.05-0.2x-0.05+5/4=0解方程

0.2分之0.1x+0.05-0.5分之0.2x-0.05+5/4=05(0.1x+0.05)-2(0.2x-0.05)+1.25=00.5x+0.25-0.4x+0.1+1.25=00.1x+1.6

X-(0.2X+10) -1.2*(0.2X+10)+8=0.36X 怎么解

X-(0.2X+10)-1.2*(0.2X+10)+8=0.36X0.64X-(0.2X+10)(1+1.2)+8=00.64X-0.44X-22+8=00.2X-14=0X=70

4,1.2,0.36,0.108找规律填空

4,1.2,0.36,0.108依次乘以0.3则0.108x0.3=0.0324希望对你有帮助,满意请及时采纳,你的采纳是我回答的动力!
