-40,-20,-10,1,0.1,0.01,0.01,0.001,0.0001,0.00001有什么规律

电压互感器10/0.1/0. -40,-20,-10,1,0.1,0.01,0.01,0.001,0.0001,0.00001有什么规律 解方程 120×40%+120×9/20+x=120 0.1×0.1×0.1×0.1x=1 10个0.1相当于100个0. Q=mc(t2-t1)=0.1*2.1*10*10*10*(40-20)看不懂麻烦解释一下 √40+√0.1-5√1/10=? Matlab程序画图问题写了一个程序,目的是显示一个分段的函数.在x属于0到10之间,y取1；x取10到20之间y=0.1x+2；x大于20小于80时y取0.程序如下（只有几行就不注释了,）x=(0.1:0.1:80);y=zeros(1,800); for i=1: 1除以0.1除以0.01除以0.001除以…除以0.（00…10个0）01 1/5+1/10+1/20+1/40=?用巧算 从10里面连续减去多少个0.1,结果是0. 10分之一可以写作0.1那么100分一是0. 1+2+3-6-7+9+10-11+10-20+14-20+30-40+50-40+40+40-70=? 找规律5,1,10,4,20,(),40,10,()... 10/x+(1/40+1/X)20=1 含水10%的酒精密度0.8·0.9+1.0·0.1=0.82错在哪里?10/(9/0.8+1/1)=0.816不是0. 含水10%的酒精密度0.8·0.9+1.0·0.1=0.82错在哪里?10/(9/0.8+1/1)=0.816不是0. 3x+0.1+2.5x=1+0. 0.1X-0.2/0.02-2X+1/0.
